Drivers have a very strong tendency to use what are touted as safety improvements as performance improvements, braking later for instance. This is called risk compensation, or more accurately, risk homeostasis. Read John Adams Risk.
One famous study looked at the effects of anti-lock braking and found higher speeds, closer tailgating and later braking.
I think you missed the whole point of my argument which was actually about removing risk compensation by removing the monkeys.
That is a very good point, and as long as humans are controlling their cars they will make their own decisions about risk, so any "safety"intervention which does not change the human tendency to take risks will fail to reduce road danger.
I was taking issue with one of the assertions which you used to make this point, not the point itself.
The roads are not really getting safer for all road users.
In our system of dodgems the dangerous users are insulated from the consequences of their actions, but the vulnerable keep out of the way, adopt flimsy protections, and take more and more care, abandoning certain roads.
As Smeed found, denser traffic in itself produces fewer collisions per vehicle, which is good for the vehicle users, but not always much consolation for us.
|I am afraid I will always express my disagreement with the idea our roads are getting safer. Over my lifetime the proportion of children of primary age allowed to make their own way to school has shrunk by a lot.
In 1971, 80 per cent of seven and eight year old children were allowed to go to school without adult supervision. By 1990, this figure fell to 9 per cent. Road accidents involving children have declined not because the roads have become safer but because children can no longer be exposed to the dangers they pose.
