Like in Finland where speeding ticket fines are based on your income. For instance, in one well known case a businessman was fined €121,000 for going 82 km/h in a 50 km/h zone.

And before anyone calls this crazy, note that jail time costs you your time, whatever that's worth. This is the same idea without the physical incarceration.

That's considerably more than someone near me who was doing 245km/h in a 90 zone (Well 55mph which is 89km/h). I still don't know why that person didn't lose their license (other than the obvious fact that they were rich enough to afford the Lamborghini that they were driving in); it wasn't just any 55 zone, it was one with a reputation for being dangerous.
