The simple reason is that most criminals don't believe that they're going to get caught. Let's face it, the reason why states/countries have the death penalty isn't for deterrence. It's because they want vengeance.

Humans are not motivated or deterred by the size of the punishment (up to a point) - the real question in our minds is "how likely are we to get caught?"

Your chances of getting caught speeding go up if there's a cop car nearby, so you slow down - don't want to get a ticket, even a $10 ticket! If your car could detect speeding and you would then receive a ticket in the mail, speeding would disappear completely overnight.

Cutting down on roadway deaths often involves just putting more officers on the road. If you see a cop car, you go slower because you don't want to get punished.
