You have this in most of the US, and people rail against any attempt to bring it in because they're frightened that garages will not give them their cars back if they think it's got something wrong with it.

I've seen people driving cars in the US that you wouldn't even be able to get a scrapyard to take in the UK, they'd tell you to just sweep it into a bag and put it in the recycling.
