Earlier quoted context omitted.
With a fine of 103,000$, I'd assume the person would be willing to pay a ton of good lawyers to try and fail the ticket. It would probably discourage wealthy people to drive fast, but the price in trial/lawyers would probably be too high for the police department for it to be feasible (also, if the ticket lacks proofs, I assume the defendant could file a suit against the departement?).
Well this of course shows how things might work in one country but not in another, for example in some countries if you fight and lose you can be ordered to pay the opposing counsel. That would nix that strategy if the Fins have such a system in place.
I'm still curious as to how one can prove without reasonable doubt a ticket (camera?).
