I also think your sons analogy is flawed. Presumably he has been doing the journey to school in the past and has learned the safety rules......and is quite capable of ensuring his safety.( though any one of us could suffer the fate of being mown down by an out of control vehicle)
And of course he doesn't want to be deprived of his computer games.....children who have had such privileges are reluctant to give them up.
