I suppose people would take getting into and driving a car more seriously
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...
