At which point you can be happy that the rich person is voluntarily paying the 3 cent fine instead of the 1 cent parking fee.
If you made it a $1000 fine vs. a 1 cent parking fee then they would pay the parking fee, but how is that actually better? You convinced them to spend more of their time keeping track of how long they had before having to put money in the meter and as a result you ended up with less money. Net loss to everyone.
Meanwhile now you're creating a bunch of perverse incentives for rich people to register their cars in someone else's name or waste thousands of man hours on both sides to contest an ordinary parking fine, and creating a bunch of perverse incentives for governments to pass vague, misleading, counterintuitive or impossible to comply with laws so they can jump out of the bushes and impose massive fines on anyone who walks by with money in their pocket.
