What is the purpose of a speed limit.
Part of the time, the posted limit can be unsafe - on some roads, you could never reach the posted limit.
We are constantly advised it's not a target, so why are they there?
If the limit is NOT there, then drivers will do what exactly - drive faster and faster until they come off the road and kill themselves? Or somebody else?
If nobody can police the limit effectively, then it is not doing anything useful, and is easily circumvented.
Since we know that the maximum safe speed varies according to
conditions, driver ability, vehicle standard, etc. then surely it would make sense to replace speed limits, with something which recognised all the variables which affect safety?
I believe we already have it... Driving Dangerously. Anyone caught driving dangerously can be prosecuted.
If their speed is inappropriate to any of the variables I outlined, prosecute for dangerous driving.
If they have a bald tyre - driving dangerously.
If they pull out of a side road without looking - driving dangerously.
If they tailgate - driving dangerously.
If they are using a mobile instead of paying 100% attention to the road - driving dangerously.
Obviously we would need police officers to make it work, and evidence could be furnished in more subjective cases by in-car video.
However the really bad drivers would soon be taken off the roads.
