Swiss dude gets a 98.500 Frank fine for tailgating. Similarly someone in Finland got a €121.000 fine for speeding.

The problem with these income adjusted fines is privacy. Finland has a central database with everyone's income that cops can apparently just access. It's effectively a kidnap shortlist. Though to be fair, these guys were already flaunting wealth so for them the additional risk is marginal. But everyone is in that database.
