> Rental cars

That's a whole new can of worms though. Their scams can be a lot more expensive, and are usually after the fact (although they'll try them at the pickup counter too).

It's one of those things I will specifically always arrange through a third party that covers insurance as well, which is really an insurance against the rental companies scams.

Yeah, I don't think I'm ever getting that €600 back from Hertz Calais. Still bitter about it.
