RichardB touches on the reason I actually agree with the way the law is framed currently. 30 repeaters need to be either mandatory or prohibited, there can be no grey area.
Imagine if 50% of 30 limits had repeaters. What message would you then get if a road didn't have any? Is it 30 or isn't it? The more roads that were fitted with them the more chance you'd have of wrongly interpreting the lack of them as meaning a streetlit road was unrestricted.
As it is, if a road is streetlit then we assume 30 unless proven otherwise, which gives us the best possible chance of hanging onto our licences! Let's keep the signage as simple as we can, rather than encouraging more of it.
The problem has only really arisen due to over-zealous enforcement of 30 limits on roads where a higher limit would be sensible and appropriate. If we could stop that then the problem would go away.
The last statement is the crux of the matter. The over-zealous enforcement has lead to a problem that didn't exist before. There are very many roads that have street lights that clearly aren't intended to be 30 mph limits, but which don't have repeater signs. There are others where the repeater signs are so far apart, it's difficult to know whether it's supposed to be 30 or another limit, so some drive at 30, others at a higher limit. Other roads have lighting that doesn't meet the requirements of street lighting, so a 30 mph limit does not apply. Some drivers may know that and some don't. Drivers have traditionally used common sense, and driven at an appropriate speed - but with automated enforcement, it's just not possible to rely on this any more. The whole system is an absolute farce.
I simply don't buy the excessive cost argument (From a local/national Government standpoint, anyway).
IF you believe that breaking the speed limit costs lives, as the authorities persistently claim, and that the cost of each fatality is £1.4m, then there's a fair pot of money to go for by installing repeater signs. Each one would only need to be at, say, 600 yards. I would guess that they would cost around £100 each to install, so that's 14,000 of them for each fatality - covering a total area of, say, 3,000 miles of roads. I don't have a feel for how large an area that would be, but you're probably looking at a small city or large town. One life saved in a whole city to pay for the lot.
On the other hand, if you don't believe that breaking the speed limit costs lives, then yes, they may not be needed, but then rigorous enforcement of the speed limit is, at best, a waste of time.
The law as it stands on repeater signs, and the rigorous enforcement policy is totally incompatible with one another.
