Some people really just need to find out for themselves. All the talking it through will not convince them. Everybody is different. Even between my two boys, one is going to do it anyway, and one will be too busy thinking about it to do it. Speaking of different, I do remember friends as a kid that went through a phase where they believed "no, they won't hit me or else". The "or else" was the driver getting in trouble, being sued, going to prison, something. I never thought any of that would fix me, and continued to look.
