Here's one that's not as consequential as other posts here. It's not going to change the world, but would make things slightly better.
Split lock washers are worse than useless. They're supposed to be a spring against the bolt to help resist it turning back out over time. They don't. If anything, they make it worse.
Here's a NASA publication on fastener design (because of course there's a NASA publication on fastener design): https://ntrs.nasa.gov/citations/19900009424
This was published in 1990, but we're still using this shit. Stop. There are many other kinds of fastener locking that work, like nylon locking nuts or threadlock, and we don't need these.
This video has a great comparison of different locking nut systems and how they hold up against vibration:
