My son will be 16 in 3weeks and is already driving.   I am going to let him drive because that is the natural progression of life.... to shut him off from that would be wrong.  I've educated him and I will put stipulations on his privileges.

Teaching him to weave in and out of traffic at high rates of speed would be setting him up for potential disaster.

Having a child who paddles is a natural progression, teaching him/her to huck off a V is setting him/her up for potential disaster.

Accidents happen, you cannot live in fear, but I'm not gonna go driving through crack central with my doors unlocked and my windows rolled down on a Saturday night. -  It's just not wise.

I see you have experience with children, but unless they are your own blood, you just don't understand.
