As a Swiss (who never got a serious fine thus) I might bring clarification. What you refer to are what we call "day-fine" but official name is "pecuniary penalty". These are not decided by the police and not just sent home with an invoice. It happens only for serious crime and infraction. You will get to the court and the judge will define a number days you get fined (between 3 and 180 for all infractions and up to 500 for important fraud or money laundring). Then the justice require an extract of tax report and define the cost per day-fine (between 30 and 3000 CHF more or less same in USD).

If the person don't or can't pay, it will be converted in prison time (not a 1-to-1 rate).

For speeding, this could happen if you over speed more than twice the limit (more or less) outside highway and 80km/h above on highway, which mean starting at 200km/h on section with the highest speed limit of 120km/h, after all margins and uncertainties deduced, so you must be like 210km/h on your speed-o-meter to reach this. Which is already quite crazy (if you are not from Germany).

Morality, if you want speed like crazy, go to German, no fine on unlimied sections.
