Personally, I think there should be a uniform age for driving, alcohol consumption, purchasing cigarettes/porn and voting etc instead of having them be 16, 21, and 18 respectively. There is something f***ed up when kids can be drafted to fight in a war, but can't be at the age to drink alcohol.
There are still people that drive like maniacs when they are older. Coming home one evening, there is a curve and a no passing zone near my house with a 55 mph speed limit. I am doing 60 and the car behind me passes me on a curve [illegal] and passes in a no passing zone [illegal] while going waaaaaay faster than I was [illegal] Turns out to be a squad car with no lights on. There is an adult that broke 3 different traffic laws and could have caused an accident.
People drive like maniacs no matter what their age...some people can just get away with it and not get busted.
Uniform driving laws would take the issue out of state hands where it should be. The farm states need to have younger driving laws than the urban states.
It is so sad that some people don't have enough responsibility to give up the keys when they obviously need to.
