They have had at least a couple of instances of over $100k speeding tickets, for example.
I've become rather favorable of the idea ticketing proportional to income/capital. It's always bothered me that, in a system where everyone pays the same ticket price, essentially, a rich person can just eat a ticket as simply the cost of driving. I think that it should affect them at the same magnitude as anyone else. One thing that pops into my mind, however, is what happens if someone gets their ticket payed for by someone else? For example, what happens if a rich parent's child gets a speeding ticket? The child, who may have a very low income, and, as a result, a very low ticket price comparatively, could have that ticket payed for by their parents, so the punishment wouldn't affect them as much as someone else who was poorer.
