Internal combustion engines require intense tolerances. If your cylinder head is 1mm out of spec you're going to have serious problems.
But if the wire winding bundle for the electric motor is 5mm out of spec? You'll be fine.
The areas in a Tesla where tolerances are actually important- the batteries and PCBs- are subject to completely different engineering practices. Nobody's going to get cross trained from fitting door panels to placing SMCs... which is done by a robot anyway.
Do you (literally) kick the tires of a car before you buy it?
Engines aren't built on the body assembly line, they are also subject to completely different engineering practices, and have their own set of workers. And robots, too!
If they wiring bundle is 5mm out, you're going to have a bad day, shits going to burn.
If the doors are misaligned it either means the chassis is deformed, or at best the hinges are misaligned.
That doesn't bode well to what happens in a crash, or if it rains. Are the seals oversized to account for slop? what happens when they get old?
If I'm dropping $100k on a new car, I want to make bloody sure its built well. That doesn't mean that people won't buy them, far from it.
Look, I get it, Tesla is new and shiny. But lets not over-rate them. They have parts that are very well built. but the software, chassis and interior are not part of that.
Yes.
