tbh I wouldn't mind the peed limit being higher but introduce some sort of driving lic and exam for it with periodic re-testing. Also re-testing should be mandatory for car drivers too. Both theory, practical, reflex testing.
I ride a bicycle, bike and drive a car and the ammount of crazies on all sides leaves me speachless sometimes. I see cyclist cutting off cars and shooting into a roundabout just because cars will avoid them. I actually had a crash becasue of a retard like this and I chased him until I caught him. Took him to court and won.
On the other side of the coin - I see cars taking turns without checking their mirrors, overtaking while in a queue without making sure no cyclists are passing by. Smashed a bike to bits because of 1 twat. His insurance paid for the bike and treatment.
P.S. I'm not a perfect driver but people these days lack consideration and defensive driving(even the notion of it is foreign now)
