The LLV is all chunky aluminum panels, chunky switches, overbuilt engine, beefy drivetrain (especially when it only needs to handle 90hp), etc. They're far from efficient or well packaged but they're basically indestructible and if something does break it's a piece of cake to swap it out.
The Canoo is pretty much the opposite. It makes way better use of materials and packaging but as a result it's not overbuilt to the same degree. It's almost certainly designed around being a passenger car which only need to survive ~100k miles before things are allowed to start falling apart. With everything being so tightly integrated you can't be as granular in replacing components. Whole assemblies/modules will need to be replaced in one expensive swoop.
I'm really curious what the longevity of these things will be. There's fewer moving parts and regenerative braking to help with the mechanical side of things but electrochemically there's way more going on. I hope they work out but even if they don't Canoo should get some really good real world test info they can use to learn and improve.

It's a fancier version of the electric dog collars. If you go over a perimeter line it'll turn on a parking brake for that one wheel.

There was a prototype that popped up on ebay out of nowhere back around 2011. Seemingly made it pretty late into development before the idea was canned.
It's pretty common for a CMM to be in its own climate controlled room. Parts will be placed in the room and allowed to reach reference temperature for a several hours prior to measurement.
On production lines you usually skip the absolute measurement of a CMM and use go/no-go gauges. One should fit, one should not. They'll be made of a material with similar thermal expansion coefficients as your parts. As long as they've both been sitting around for a while they'll be at the same temp. They'll have expanded or contracted the same amount from reference so their relationship of go/no-go will still hold true.
The whole field of metrology is a never ending rabbit hole - really interesting the more you get into it.
10 micron (0.01mm) is pretty reasonable tolerance for a lot of stuff. The laminations in Tesla's motors will be held to somewhere around that, possibly even tighter. Things like motor winding insulation coatings will be far tighter.
For something like body panels or plastic interior pieces it's utter overkill and a waste of resources.
The dead silence when the Fallout title came on screen is pretty telling. Everyone was rolling through the possibilities in their heads about just how mediocre, unimaginative, and unmemorable this will be after it doesn't get renewed for a second season.
Tangentially: Microsoft Teams and SharePoint web infuriate me daily. All the functions that should be separate programs are rolled up into one inseparable window forcing you into a single task workflow.
Want to have two folders open at once that you can drag between? Want to copy a file to your desktop? Read a message from a colleague while looking at a planner item? Pretty much any basic task that Windows 95 can handle with ease? You're screwed.
These are all things that should be separate programs handled by the OS and a samba share. The MS Office ecosystem has regressed massively over just a few short years thanks to teams.
There's a station I use regularly that has to have some sort of commercial plan. I regularly see cop cars, UPS trucks, and one time a yellow cab filling up there.

Although I'm sure the headline is true, at least with my industry it's a little misleading. All we did over the past few years was cut in Mexico as middle men.
There's no cost effective domestic source of a particular raw material so it's traditionally been purchased from China and turned into a product in the US. With various tariffs and labor costs it's now cheaper to purchase the same raw material from China, turn it into components in Mexico (thus a Mexican product), and then do final assembly in the US. On paper we're importing things from Mexico but the majority of the money still ends up in the same place.
I'm curious if that's the case for other industries.
