You deal with thermal expansion the same way you do with continuous welded rail.

I think a better example is airplanes. You run at high altitudes to increase efficiency due to reduced atmosphere.

Why is a vacuum (holding a tube in compression and 10-14psi ) harder than pressure (holding the tube in tension at 200-1500 psi).

Listening to YouTube, playing music from my sd card. Changing routing instructions. Adding stops along the way. Avoiding highways, allowing highways. Asking what the exchange rate between the euro abd the dollar is. Asking if European chickens are smaller than American chickens. (And probably other things)

You deal with a different sort of people than I do.

It is unlikely that I will ever buy something newer than 2005. I’m in a 1994 right now.

It just needs to to be better than humans, not perfect. That would save lives.

I refuse to own a car that doesn’t have a DIN slot for my own tech.

A crippled version of my phone.

When I last did a TCO analysis of printers brothers came out on top by a big margin.

Can you provide case law? I’m interested.

What was the one that didn’t involve guns?
