Anecdote isn’t evidence, of course, but I don’t recall the last time I had to dodge a loose trolley in a car park (in the UK, where the deposit system seems ubiquitous).
I still see them in canals, etc., but that’s not really the same issue.
A less widespread means of combatting that one is to disable trolleys if they’re removed from the premises. No idea how; I’d guess magnets.
[ETA: seems to be a variety of RFID]
Which is a European company. Interesting.
