One factor that your average car driver has a bit of trouble getting their heads round is just how jolly quickly even modestly powerful motorbikes can accelerate



You mean if they have even seen you behind them at all.
After all, they have so much to do....satnav, mobile-phone, ICE and the drink-can in its dash-mounted holder.
As for acceleration of bikes.....mine goes from zero-mph to 60-mph in 3.4 seconds...admittedly it only manages 136 mph maximum....but that's due to the in-built power limiting and rpm limiting....
And when/if they get around to fitting their stiff-throttle limiter/warner, I hope they appreciate that it means that the roll-off of the throttle would also need to be sorted...you just cannot have a throttle that snaps shut fast....on my bike the fully-shut throttle at high engine speeds means that the engine is just not "running" at all....

It’s all just meddling for meddling sake! KISS FFS!

There’s already enough technocrap on my bike to make me want to sell it and get something from the 80s. Same goes for cars :x

How long will we have to wait before a reset button becomes standard on all vehicles? (Rhetorical).

Stop the madness!!! :hissyfit:

IMO there is a fundamental flaw in all these speed limiting/sensing/warning schemes .... it all seems to assume that that actual numeric speed in isolation is of huge importance for road safety ... Where is the evidence to support this? Can any of the perpetrators of these devices actually give much evidence of benefit for the effort involved even if they do work?

IMHO numeric speed on its own has got very little to do with road safety ... Some years ago ... before all the speed camera b*ll*x I had a motorcycle which did not have the benefit of having a working speedometer or rev counter ... they were broken and way too expensive to replace. Was I maimed daily? did I crash all the time? were other road users scattering in terror at the loony with no speedo who was sure to mow ever child in his path down? The answer to all those is of course no, in fact I think my driving improved a fair bit during that period, can't recall even having any near misses.

Unless I just got very lucky for 2 years and about 20000 miles or so I'd say there isn't much of a tie up between knowing your numeric speed and safety.

I agree.

The focus is all wrong, if safety really were the objective.

If you're riding along and the system detects (or thinks it detects) a change to a lower limit which is considerably slower than you're going at the time. If the throttle then suddenly tightens up, and you don't have a firm grip on it, it could snap shut.
Because of the low gearing and relatively light weight of a bike, the resultant engine braking could be considerable and, if you happen to be leaning through a bend at the time... :shock:

If it snapped shut, I agree it would be a problem, and I have no idea what sort of forces would be involved with this system. Also, the effect you describe would be worse, if you were in a low gear. In fact this system would kick in just at the time you would be likely to be changing gear, the the speed limit was changing.

Hmmm... Well I have been a biker, even at times when I haven't owned one, since 1975. (It’s always in your blood :) ).

Back then I remember on more than one occasion being told to leave a pub, they refused to serve us and told us to “get out”. :x This is unheard of today and bikers have become respectable 'clean' decent citizens with jobs other than bricklaying.

I still find it strange to this day that back then, in the days of 'Love Thy Neighbour', black people could go where bikers were routinely kicked out! My black friend found discrimination when he was actually on the road and would most often get stopped when spotted by a traf pol. Hard to believe this was only 35 years ago but it still looms large in my living memory and makes me sick to my stomach.

Thankfully, both racism and bikeism has all but come to an end and I don’t think bikers are quite as persecuted as you suggest. I think all people on the road with an engine either between their legs or under a bonnet are persecuted these days.

I would agree with you if you were to say this country has a 'downer' on bikers more so than on the Continent. But I think it's a more a Laissez-faire thing than anything. If you are doing no harm then get on with it...

We are culturally stunted, or perhaps I should say saturated.

:bunker:

Again ,slightly OT -but I've for long years had a high regard for bikers .Started when one night I borrowed FIL 's Robin - and had fanbelt failure - hardly had bonnet open when I was surrounded by bikes .Next thing a fanbelt appeared ,and before I could say Reliant Robin ,a new belt was fitted .Once it was started and running ,they disappeared. My son in law is a biker ( he not only bikes ,but he 's into fixing etc ) ,so my daughter has been bitten with bug ,and my grand daughter is mad on bikes/quads .Their friends -come round to theirs at times -all leather /beards etc - but the salt of the earth . From what I can see - the last Government succeeded on setting motorist against motorist , but bikers had been vaccinated against the infection .Anyway -I'd have liked a bike in my youth ,but practicalities stood out against it - if you lived in the wettest part of the UK (with narrow roads)- WHAT WOULD YOU CHOOSE - bike ( where you might keep dry and not have to worry about water on the road and ending up mashed against a drystone wall )- or car -(where you kept reasonably dry-had another pair of tyres to cope with water,and a lot more metal to get between you and an idiot). I chose car .

yeah i remember the days of not getting served in pubs but i dont remember ever having to put up with the harrasment of some of the police forces in this country these days when i try and go to a few bike rallys then pulled over for no reason for a so called spot check gets a bit boring arfter the 3 rd time ,,never seem to get pulled in my car for a so called spot check , :soapbox:

As a biker I have avoided collisions and got out of trouble using the throttle and seriously hope such a system is not introduced.

When they are field testing of this (If it comes to that) hope they test this system out while navigating a patch of diesel on the road. :?

The system will be designed by pedal-cycle riders, built by pedestrians and tested by car drivers.
Any problems will be blamed on motorcyclists not appreciating the technology and being "obstructive"
I well remember not being allowed in pubs, and being pulled-over by police on the trek down the (fairly new) M1 (about 30 of us).
I still ride bikes....except now it's a BMW.

I believe that this is happening partly as the Police are less experienced in Traffic issues, and so do not recognise real problems from the possible problems, hence stopping people that would previously have been left alone.

Lets return to the post topic - "SPEED LIMITERS" ,it was for bikers , but it also applies to cars ,be they 45BHP ,OR 450 bhp - they've all got one .In the case of bikes -it's the rider's wrist ,in the case of cars- the right foot . They've got a licence - respect it , or what legal right have they got to restrict it ,if the licence conditions are being met .

EU =another stupid idea . Now if they could come up with an idea to shock a cyclist for
using the pavement as a second lane
jumping red lights
violating the HC
using footpaths in public parks as cycleways
etc/etc
that might go some way to saving life and stopping injury .
