My wife and I were talking with one of our friends about our CJ's right of passage. He also has a son (one of CJ's friends) that is also going through the same rite. We both spoke about being extra careful on the road nowadays given both of our son's being out there :-).
He also mentioned a solution to the proverbial "how many kids can you get into a single car?" problem for teenagers (yeah, there's laws against a teenage driver carrying more than one other passenger in Virginia and many other states, but kids don't always listen to laws) -- a mutual friend had the policy of providing their kids with pickup trucks only.
Pickup trucks with no extended or crew cab. The kind that only fit at most 3 people. Much stronger restriction than any law.
Seems like a good idea to me although I don't know what's up with this idea about providing a car for your kids... I had to earn my own money to pay for my own car.
