Of course they are mistake prone, but with a semi-auto and careful instruction, they are fine.
I actually wrecked two cars as a child because my parents left me in the car while it was on. It didn't matter what they told me. You can only protect your kids so much and you can do all the talking you want (which is what I do), but kids will be kids.
Weed and alcohol certainly do kill a ton of kids/teenagers.
Ok giles, you win. Teach your kids how to drive cars, use drugs, sword fight, fire semi automatic weapons and have sex and an early age. That way if they ever land in those predicaments, they'll know exactly what to do.
