This problem just doesn't exist anywhere else in the world. Ambulance is just another truck. There are some fees involved with having priority on the road and some regulations, but it's just another truck. It won't cost (to anyone - i mean OF COURSE it is free for the actual patient) over a hundred euros or so to do a simple across-city ambulance ride anywhere in EU, maybe 2x the price of a cab.

That's corruption and nothing more. End it and imprison everyone who ever had a tangential relationship to this system, for life - to ensure no one will try to pull this sort of "regulatory capture" again.
