A poor-middle class guy gets a ticket, and it can affect their ability to pay rent.
A rich guy get's a ticket and he tells his wife over dinner.
How about tying your first ticket(reasonable mistake--like a California stop, etc.) to income, but only every 5 years. If poor person get's another ticket in five years all fees go back to normal levels?
There would be upper limits on ticket price, so millionaires wouldn't be gouged too much. I think they tried this in Switzerland, but the law didn't have upper limits for the wealthy? Some guy got a $100,000 ticket--which is crazy!
A $500 ticket can really cause pain for students and the poor? I have thought about this since I was sixteen?
