I use to have an old lexus with 240K miles on it and they didn't even bother to give me a warning. I would tell them I was sorry and they would pat my car and say slow down. I guess they figured I couldn't afford a ticket.
But I bought a new car this year, and now they have no mercy. If you look like you can afford a new car, they think you can afford a ticket. So in addition to a car payment and higher insurance because it isn't yet paid for, I have the expense of more tickets.
