Are you sure you don’t read the Daily mail?
Just to be clear, I was almost killed by a speeding motorist who was racing his mate. The road in question was de restricted but there were a couple of sharp bends which they removed after my accident.
When the French stop tail gating the accident rate will fall because it gives time to avoid, going 10kph less doesn’t change the basic bad style adopted. I try to leave a decent distance but almost every time a french car overtakes me only to fill the space I was leaving and I am usually doing near the max for the stretch of road. The french seem obsessed with forming a train separated by the shortest length possible.
As to drink, why are the accidents where people have been driving not at or just over the limit, they are multiples of the limit higher x2, x3, x4. If you blanket ban alcohol, these people will still drink. still have accidents and still kill and injure. The Law punishes them as it does now. The limits are there, established by experts. Those that flout the law, flout the law, speed, drink, mobile phone, drugs etc.
