basingwerk, a couple of illustrations for you.

Let me introduce you to Mr Perfect. Mr Perfect does everything perfectly. He can't help it, he was born that way. His work is perfect in every detail, at home he hangs wallpaper perfectly straight and puts up shelves pefectly level, and his wife is a very happy woman (fnar fnar :lol: ). Of course, he is a perfect driver too. But unfortunately Mr Perfect is not perfectly happy about his insurance premium, which has just gone up. The insurance company has told him that this is because his job no longer requires him to do 12000 miles a year, but more like 25000. He pointed out to them that he is the same person and his driving abilities are unchanged (being perfect at dealing with other people he was far too modest to mention that his driving skills are, in fact, perfect) regardless of how many miles he drives. However, the view of the insurance company is that Mr Perfect lives in an imperfect world, and the fact that he now does 25000 miles a year means that the risk of someone hitting him is now just over double what it was last year. Perfect or not his exposure to risk posed by others has increased, even though the risk he himself poses to others is the same as before. Zero actually. He is a perfect driver after all.

Getting away from driving entirely, lets consider football hooliganism. My sister Mini-me is far more likely than me to encounter football violence because she's a football fan. I can't see the attraction of football myself, and would far rather watch rugby even if it means watching Wales beat England :wink: . Actually I'd far rather do the hoovering than watch a football match - I really do find it that uninteresting. But I know I'm in a minority, and Mini-me certainly doesn't agree. She goes to matches from time to time, though more often she watches them on the big screen in the local pub or at home. Nothing's actually happened yet, but since she does go to matches sometimes and she does sometimes watch them in pubs packed with (a) lots of other football fans and (b) booze, there's a better chance that she'll encounter a massive drunken set to than I will. Now, what does that tell you about Mini-me's character? Does it tell you that she's the type of girl who'll smash the bottom off a beer bottle on the edge of a bar before sticking it in someone? Or does it tell you nothing more than that she's got an interest that sometimes brings her into the same environments as the sort of people who do smash the bottoms off beer bottles? For the record she's a sweet kid, a non-smoking teetotaller who studies rather harder than she plays and is waiting to find out which uni she got into. And in the unlikely event that she lurks in these forums and has worked out Gatsobait's secret identity, she's probably extremely embarassed as well. :lol:

The problem with that is this. Risk is made of components. Some components we can control if we try, while we can’t control other components, no matter what we do. As far the insurance company is concerned, once the limits of it’s assessment granularity are reached, all the residual components are weighted randomly, i.e. he may be perfect in his own eyes, but he is just another jostling car in the road system, as far as the system goes.

To you, Mini-me is a person. To the system, she is a statistic. That is unfortunately inevitable, really. By chance, the risk business works accurately enough to make good profits!

A weakness in your main case is that it is an absolute one, based on the (so-called) fatality gap. It does NOT account for more cars and longer journeys. Even if it did, you are missing a good way to avoid the risk of a dangerous activity – just don’t do it!


Nah. Rubbish. The fatality gap is calculated from the fatality rate figure.

It's our business to control (evaluate / estimate / whatever) the risk of the activity - Not to encourage the activity, nor to discourage it. We recognise that people are going to drive, and we'd like them to do so as safely as possible.

I feel sorry for anyone that can't make the distinction.

You will suffer misunderstanding because driving IS a social / political issue!


That's not my problem. If others can't tell the difference between social/political values and safety values, then that's very much their problem.

Back to the original thrust of this topic, can anyone see the connection between voiding insurance if speeding etc. and the recording system noted in this post:

http://www.safespeed.org.uk/forum/viewtopic.php?t=3405

The insurance companies will be all over this in an instant if it looks like they can avoid paying out.

You got that right - it IS taken from the raw fatality rate figure, not the deaths per billion vehicle km driven. That is why is it false, according to your own criteria, set down a couple of posts back.

The problem with that is this. Risk is made of components. Some components we can control if we try, while we can’t control other components, no matter what we do.

That's my point. However, you seem to assume that the level of each risk component rises and falls in unison. In the case of our hypothetical Mr Perfect the risk of the insurance company having to pay out increases not becuse of Mr Perfect himself and the risk components that are under his control, but because of those components that are outside his control. And only because of that. In the same way while an imperfect but still highly skilled high mileage driver does have a somewhat elevated risk of causing a crash due to having more opportunities to cock things up, the risk of suffering a crash at the hands of one of the large numbers of tossers and TIBMINs on the roads goes up that much more simply because he's spending more time among them.

To put it another way, let's assume that you are a skilled driver who does 25000 miles a year and will on average cause a collision once every billion miles. Hey, you're pretty good. You're only likely to cause a crash every forty thousand years :oops: Getting a bit unworkable, so let's say every million miles to make it once every four decades. Still not bad though :) , but let's say that about once every 500000 miles a TIBMIN hits you. That means that you'll be involved in 5 crashes every 40 years and make an insurance claim about every 8 years and 10 months. But only one will be your fault. Now lets double your mileage. All other things being equal you now have an average of two own fault crashes every forty years, but are going to be involved in 8 more that are caused by someone else. And your insurer is going to be unhappy as you're now making claims at the rate of one every four years. Clearly the relative size of the risk components doesn't change at all - initially you caused 1 in 5 of the collisions you were involved in, and now you cause 2 in 10. What has changed in real terms is that while you are likely to cause one additional accident in that forty year period you are likely to be on the receiving end of FOUR more. But the insurance company has to deal with all of them regardless, and of course if there's any two way finger pointing they usually take the easy option of splitting the costs 50:50 with the other person's insurer. That's why low mileage drivers pay less.

Mr Perfect does everything perfectly, remember. So he is also a perfectly objective judge of people's abilities, including his own. If he says he's a perfect driver then he bloody well is! :P :lol:

What are you on about? The fatality rate is specified in deaths per BVKM. When total BVKM is known fatalities can be inferred from the rate figure.

I can see that Clarkson better not have made a claim when he took one to Monaco :twisted: Seriously, I think it all depends on whether or not the data really is collected and whether or not it would actually be used. It's not practical to start ripping bits of the car out, so the only solution is to examine the small print of policies and cancel them if you don't like the terms. I expect the cheaper the policy the harder the company will try to get out of having to pay claims, so it might be worth paying extra for one that isn't so restrictive. The obvious worry for drivers is that all insurers will end up doing it, but in turn the worry for the insurance companies is that one of them might not and get a lot more business when it becomes common knowledge.

But that presupposes that the alternative to doing something is doing nothing, whereas in practice the alternative may well be doing something else that is more dangerous.

Getting back to one of the earlier arguments, Mr. Perfect's risk of being convicted for a speeding offence would also go up because of his higher mileage - so his insurance premiums would be loaded even more.
But, ironically, and bearing in mind that Mr. Perfect will never cause an accident, his risk of someone else hitting him goes up with the time he spends on the road - but the higher his average speed (and therefore increased risk of conviction) the less time he spends on the road for a given mileage, and so the lower his risk.

However, speeding fines are indicative of exposure - drivers who do greater mileages are on average more likely to pick up speeding fines and on average more likely to have crashes. So more fines does mean more risk, but frequently not because the behaviour is a risky one.


If you get crashed into, it is irrelevant whether the cause of the risk was because of poor behaviour or excessively high mileage, isn’t it?

I don't think so for two reasons. First high mileage can never be a cause of a crash, and therfore cannot be the cause of the risk either. It is simply a proxy for the amount of risk you have due to your exposure (to use Safe Speed's term). Secondly, you are assuming that a high mileage driver is more likely to cause a crash, but that is not necessarily so. High mileage drivers are more likely to experience a crash, but that could esily be of someone else's making - a low mileage TIBMIN for example. You can be a terrible driver irrespective of the amount of miles you do each year, but of course if I do 50000 miles a year my chances of finding your car in my back seat is greater than if I only do 25000, which in turn is greater than if I only do 12500 and so on. That doesn't change no matter how good a driver I am or may become in the future. It's kind of like cancer - all other things being equal the longer you live the more likely you'll get it.

basingwerk wrote:
To achieve the same low risk as a low mileage driver, a high mileage driver must be much better behaved. Luckily for me, my insurance company penalises high-mileage drivers, so that I can get a better deal.

No, the behaviour of the high mileage driver really doesn't help him avoid encounters with bad drivers, though the experience of the extra miles may just help them prevent an encounter becoming a collision. That'd be ironic as in that case it would be your putatively low risk driver avoiding a crash solely because they had the good fortune to encounter a high mileage driver, but I don't want to get into scenario building. I just said may.As I explained above, it's a numbers game. Look at it in regards to something other than crashes. Breakdowns perhaps? Would you not agree that your chances of breaking down increase with mileage? At an extreme you can avoid breakdowns entirely by never leaving the house, but leaving aside the fact that that isn't terribly desirable it tells you absolutely nothing about how well maintained you keep your car (or not, as the case may be).

This shows that a good way to increase road safely is not to drive at all, or to drive much less. Where do you say that on this ‘road safety’ web site?

:roll:


Lesson in insurance (from bloke with a harem of lovely sexed -up ravers (apart form Wildy :neko: :twisted: :lol: :shock: :? :lol: :D 8-) )

    1. They base on claims made. If you cause accident - affects no claims discount. If protectected no-claims - based on good driving record - you are only allowed one or perhaps two in given period)

    2. Our premiums were outrageously high because of Wildy's unfortunate no-faulter - but this was later sorted once we sorted it out in court.

    3. Premiums are affected by POST CODE! Jessika (Wildy's cousin) receives a teacher's discount - but this is swallowed by fact she teaches in Merseyside. Because of the "theft" risk and fact that she drives through a very congested area - more chance of theft and prang even though she's another RoSPA goldy girly. Similarly one of my brothers lives in North Yorks - but drives into Middlesborough. Likelihood of theft upped the premium and my young sister, Jan, lives in Manchester area and has same problems as Jessika.

    4. High mileage drivers always have more risk of prang and ping because of exposure. Does not follow that they are dangerous drivers. Most are average to well above average.

    5. As Gatsmate has pointed out - they do not even ask about points on licence. Perhaps they know I don't have them because my driving licence has none recorded ever against it. Suppose they just check some data base and depends on DVLA records? :scratchchin:


But in any case - find this kind of carry on will deter rather than encourage kids to take out insurance. Better to encourage Pass Plus and further training rather than focus on one element only.

The only clause I agree with is the drink/drugs one -as it may deter. But for this to work the borker must surely have an onus to point out all these traps in the small print and ensure the insured fully understands this before he signs the agreement.

OK then

Panic over. This is not an exclusion, this is not a "you are not covered" this is a "duty of care" - so what I have to do to mitigate my accident risk.

Quote:
The insured person must take all reasonable steps to reduce accidents, injuries, loss or damage. They must keep the vehicle in efficient and roadworthy condition and protect it against loss and damage.

The insured person must:

1) Not drive while over the limit of alcohol as laid down under the Road Traffic Acts or other relevant laws;

2) Not drive whil under the influence of banned substances as laid down under the Misuse of Drugs Act 1971 or other relevant laws...;

3) Not drive over the speed limit, as laid down under the Road Traffic Acts or other relevant laws;

<snip other exclusions in regard to keys etc>


Now Paul and I were just discussing this - at the time of an accident, even if I was speeding when I realised it was going to happen, I'd be slowing down when it did. And if someone parks in my boot, then their insurance is replacing my car!

I think this isn't a lot to worry about...

<ducks>

but there are other ways to mitigate risk, and one way is to drive more safely. By loading the full cost of an accident directly on the bad driver, you provide a direct incentive to improve.!


So I guess all those with their eyes glued to the speedo will be included in that category, I mean, they can't be driving safely by doing so can they? or how about the bad driver, who, although they're travelling within the limit, mows sown someone at a crossing because they weren't paying attention to the road, ie they were changing a tape or fingering their hair etc etc. will there be categories for those too?

I looks like you have switched to fatalities per BVKM at sometime, except for graph 2.7, which was the old basis for your claims. But it is worse than I thought - all your graphs end in 2001, but much more recent data is available. A cynical person might think that 2001 was a good fit for your polynomial least squares, so why not extend them, now you have the data?

Mr Perfect could explain how perfect he is until he goes blue in the face (:P ), but no-one would believe him. You are right - a good driver is still at the mercy of the dumbos, and it only takes one dumbo to kill you. Another good reason to cut yourself plenty of margin with the speed.

Yes, let’s use creative language. Perhaps high mileage drivers are simply guilty of dangerously high levels of driving exposure! Then they could be in danger due to driving without being dangerous drivers!

More modern data follows all the recent trends as far as I am aware, with 2003 as the worst year. 2004 was slightly better, but apparently co-incided with zero expansion of speed camera sites!

Updating graphs is very time consuming and that's the ONLY reason they haven't been updated. You ARE right - I should find the time, but hell, there's only 168 hours in a week...

I missed this comment in my last reply.

No. This graph (although worrying) was never the 'basis' for anything. In fact of course - if traffic had gone through the roof in the late 90s, that would have been the expected result. It's only really scary when you put it in the context of modest traffic growth.
