On the other hand, what's the point in locking up someone who (a) statistically will never do it again and (b) never intended or foresaw that this would happen?
Sorry if that's a bit blunt. It would definitely be better if people were more safety aware.
Maybe making people watch videos like this as part of (re)training of drivers would be more effective?
I guess an analogy for this is that I don't change my behaviour after I buy a lottery ticket. Sure it is not technically impossible that I will be a millionaire soon. But I don't take the precaution of lining up a lawyer and a tax accountant because the chances of it coming to pass are so tiny...
