I agree with you and when I mentioned balance between legal and a good idea I meant like this: There are lots of things that are legal or can be legal that may not be such a great idea. But, I get that if we start trying to stop folks from having things that may not be a good idea, then we open a whole new can o worms.
I completely agree with you there. I have a Mustang GT and absolutely love it, but wouldn't necessarily recommend it for a 16 year old who got a driver's license last week.
