Yeah I mentioned in a sibling comment that there are things that are too expensive to have a bunch of, so you can’t do it for everything, just relatively cheap “I can never seem to find X when I need it…” stuff.

Perfect example of anti-progress in the modern world.

My parents had a Mark 2 Ford Escort. My mum came home in someone else’s car once, as it looked similar and the key worked in it.

Mazda 323’s used to open each other too, and also Ford Lazers. These problems don’t seem to happen anymore, but at some cost.

eh... my car before that, a 90s Japanese car, had plain old dumb keys. It was stolen twice (and found abandoned twice) by joy riders who easily stole it.

I hope to be buried with my old, dumb cars :p
