here's teh way i see it... when i eventually decide to have kids, there will be a strong bond between father/son (assuming its a boy) and he will know the consequences of his actions BEFORE he ever sits his ass in the driver seat... and by that he will be way to scared to even park too close to someone... being that it would be a trusting situation and he'd be more scared of me than the wraith of God, i say sure!
seriously tho, if the trust is there, i say absolutely. if its not... no way in hell.
