I’ve seen a number of interesting things in relation to road safety lately, some of which have caused me to revise my thoughts.
First, there’s the question of retesting for older drivers. This seemed self-evidently desirable to me, based on data showing very high fatality rates per km driven and that in most collision involving older (75+) drivers they are at fault. However, a Twitter discussion (must work out how to do Storify!) following this Background Briefing showed that things aren’t nearly so clear-cut. The fatality evidence isn’t really helpful, since it just reflects the fact that an accident is more likely to be fatal to an older person than to a younger one. The differential hazard is far greater for falls, which suggests that forcing older people out of cars may not be beneficial. And overall, the evidence on the benefits of testing appears to be mixed at best (the Monash expert quoted in BB overstates the case a bit, in my view).
More directly relevant to me (at least for the next decade or two) there are some suggestions regarding cyclist: a one-meter clearance requirement for cars , relaxation of abolition of helmet laws and requirements for licensing, rego and third-party insurance. The first is obviously sensible, the big issue being enforcement. On the third, I agree in principle with licensing and TPI, the main problem being what to do about children. Registration seems undesirable until we have a proper system of road pricing.
On helmets, I’m genuinely ambivalent, particularly after witnessing a head impact accident this morning (no injury, thanks to helmet). I would always use a helmet, but I’m not happy about the claim that Australia should have different helmet laws than Europe because our roads are more dangerous, and our drivers more aggressive. Granted that this is true we need to change these conditions. The obvious first step would be to reduce the current 60/50 speed limits for suburban streets and subarterial roads respectively to 50/40. This would greatly benefit road users (including both cyclists and older drivers) who can’t or don’t want to travel at or near existing speed limits. The welfare cost of slightly lower limits would, in my view, be trivial. I have zero sympathy for those (echoing smokers and polluters of all kinds) who want their convenience to justify imposing risks on others.
The other point though relates to those aggressive drivers. Whereas the evidence on older drivers is weak, there is ample evidence that aggressive driving, manifested particularly in traffic violations, is associated with higher crash risk, as is at-fault involvement in a previous crash. The current points system is absurdly lenient in this respect. The 12 point allowance lets drivers be convicted over a serious offence (running stop lights, speeding in a school zone etc) every year without any restriction on driving, and the suspension period for violators is only few months. I’d suggest a lifetime allowance of 24 points, with permanent restrictions thereafter, as well as reducing the three year allowance to 8 points, and increasing suspension periods.
The restrictive treatment of drivers at the older and younger ends of the age spectrum contrasts sharply with the treatment of a drivers license as a natural right for the 25-75 group, to be withdrawn only in extreme cases. In my view, aggressive drivers should be taken off the road to make them safer for the rest of us, including non-motorists and those whose reflexes aren’t sharp enough to cope with the high-speed high-risk driving of others.
