I think is not just catching people, or making the populace scared to be caught, or at most that is just a small part of it. The main thing is to make it unacceptable in todays society, just like wearing a seatbelt, and drink driving. I can remember my dad purposely buying an automatic 2.8l Granada as it was easier to drive back from the pub pissed, apart from being dead, he would most likely think he couldn't do it today, as it's unacceptable, by everyone, not just the filth.
