This isn't a tax scheme. It's a traffic ticket. A $12,000 infraction is ridiculous. This system would make policing our roads about collecting revenue instead of enforcing safety standards. I don't like it.
I understand and empathize with the objection, but I don't see how this would encourage this sort of behavior. The vast majority of people would be paying a fairly low amount, so there wouldn't really be any added incentive for law enforcement aside from doing their job normally. Someone making that much money could easily afford it; I don't see why we should be saddling people who live paycheck to paycheck with hundreds of dollars in tickets because of minor violations.
Also, I think it's a bit naive to think that we already don't consider it a revenue scheme. This would at least make the current de facto reality more
fair.
