So EVs are pretty simple machines. I think we can all agree on that. Like I am not a mechanic and I can work on these things (well maybe not the tires).
But the problem isn't just that a single component in these things sucks, it's the whole design. That being said, the motors, controllers, axles, sensors, etc, can't all be entirely custom. I would be willing to bet there is a fair amount of useful shit we could "borrow" from unsupervised and unwanted cyber trucks to rebuild them into something much much better.
