It is more what was there before, the chicken or the egg, as long as the police are corruptible nothing will change.
We all know that even when an offence takes place and a police officer passes at that moment, nothing happens.
upfront, I 100% agree with you that driving/traffic training sucks and therefore believe that something needs to be done on both sides but in the 25-plus years I've been here, I haven't seen much change happen.
