Problem in the UK is law enforcement is so liberal, it actually perpetuates crime to occur. Out of the G7/8 countries we must be the one with least presence of a police force, a scant few police driving around and only unmarked cars likely to stop anyone and they will in the main be motorists. Else where in the world the police forces appear to be stronger on anti social behaviour and there presence are not just a token gesture.
One only has to look and see the anti social behaviour that occurs, boy racers and there noisy popping banging cars, my local Sainburys car park is race track most weeks nights with them meeting and racing around. Bike riders with no lights at all (I don't call them cyclists), scooters on main roads and paths causing danger, speeding cars in built up areas and as I witnessed over the weekend even over taking two or three cars to do in 30 zone. One can go on and on.
We simply don't have the enforcement to crack down harder and I'm with you Guerney fines are punitive and can hardly be called a deterrent.
