They also provide zero support

Another problem, with my desktop PC, it doesn't have a TPM, which is required by Windows 11
I couldn't upgrade even if I wanted to. It's been going fine for the last 6 years, there's no reason it won't be around in 2 years time.

Apparently Tesla's break more often and cost more to fix.

Your thinking is narrowed down on to threads. You seem to be trying to fit a solution to a problem.
Your problem is describing tasks. Tasks that may create new tasks when they complete.

Oracle killed Oracle Java
They basically told everyone to move to OpenJDK with their licensing model.

forking is not thread creation in Java.
Maybe because fork-join has been a thing for 60 years, before linux, posix, unix or multics existed.

Hertz reported higher cost of ownership for Tesla's. They're heading for another bankruptcy.
Higher cost of repairs is one of the reasons. The other was price cuts hurting future resale values.

Hertz hinted that the repair cost and higher incident of damage is a Tesla thing, and expects GM EV's to be cheaper to maintain.

Grease is fine, like in wheel bearings, but it creates lots more friction than oil
Oil, like in a diff or transmission needs to be cooler or it starts to break down.

Unless you drive down a big hill when the battery is already charged, do regenerative braking is not available.

To be fair, a CV joint boot doesn't have to deal with rotating shafts.
The bearing seals in the hub and diff don't have to deal with lateral movement, only rotational.

I can't wait to have a gearbox full of oil bolted to a brake disc.

It has 4, one on each end of the half-shafts between the hub and the combined motor-gearbox-diff unit.

That's how the back wheels can move up and down without snapping off.

It's not a hub motor.
But some of the disadvantages are:
* low torque transfer, due to small gears inside hub
* gearbox inside hub now has lubrication issues to solve
* very large reduction ratio due to small sun and large ring gear, very high shaft speeds required. which still require a CV joints for steering
* gear box situated next to brakes, oil doesn't like high temperatures.

It's not clear if suspension movement translates to shaft rotation. Maybe it does, maybe it doesn't.

What was your browser and company?

This big hole you have to fill up, you can only do it once.

For the oil to form (which will take millions of years) it requires heat and pressure, which is only going to happen once the well has been completely filled up.
