Fair enough. Then the fine shall be levied at the value of the car being driven when the offence occurred. Driving a $500 beater? Your fine is $500. Driving a $1,000,000 sports car? Your fine is $1,000,000.

While this theoretically allows the rich to drive said $500 car in order to minimize their liability in the event of a fine, it also means the rich have to drive a $500 car if that is what they are trying to optimize for, which is a decent social tradeoff.

That's a pretty interesting approach as it means you don't have to ask about how much money the person makes, which can vary.

Though it hurts poor people who prioritize their car over other essentials.
