Is that not the way it works in the states?

That's how it is in England.

3 points for a speeding offence. 12 points and you lose your license for 6 months. Points take 3 years to disappear from your license. You also get fined up to 75% of your weekly income, based on how much over the limit you were going, and there are some hard limits (100 mph?) which result in an instant loss of license. It seems sensible.

I agree that financial penalty does disproportianately affect the poor, but at least scaling it with income means the rich cannot completely ignore it either, as they could with a static fine.

Not sure about the states but here in Australia it works basically as you have described - but there is also a very expensive (in my opinion) fine for each speeding offense, and this is not scaled according to income.

Australian fines are quite ridiculous. As a student, a speeding ticket of $700 meant two weeks of my pay gone.

They really do run a mafia extortion system there.

Financial penalties and a camera system would be a nice way to get some budget needs met though. You can even do it on parkway by putting cameras at the exits and timing how long it takes from one to the other. Or, implement a toll road that charges you more the quicker you get there. Someone driving the speed limit doesnt pay, but everyone else above (or driving too slow) does, with it rising the further you away from the limkt you get.
