Quick Driving Question

Why do some people, when stopping at a stop-light with no cars ahead of them, stop about a car length in front of the white line*. I find this creepy and question the morality of people who do this. Does anyone else think we should implement some kind of penalty for these people (e.g. You have just been awarded 15 stupid points - 5 more and you are banned from the country)

* I considered the viability of such a move in certain turn lanes, but then decided it is still a stupid and creepy move.
