Mechanics work in metric mostly. You still come across some imperial sizes occasionally. Though recently that’s been getting standardized a lot better.
I mean, that might be true, but I work on a lot of shit that’s right around 20 years old. It’s mostly metric. But I keep a set of standard sockets around that I’ve had to pull out once or twice. Sometimes it’s been because of swollen bolts but sometimes I’m pretty damn sure that’s a 5/16.
I can guarantee it’s either someone that put the wrong bolt there or it’s due to rust.
All American cars have been fully metric since the 90s (with a push during the Carter years as well), Japanese cars since the 60s… Maybe you’ve had to work on a x.5mm bolt but that’s extremely rare.

Then there’s planes, and trains and also ships. Ships can have parts and systems from god knows when
