Earlier quoted context omitted.
That's a bad example. Early Teslas had 2 gears, but then got rid of that and now only have one. That got rid of the transmission and gearbox, and the car breaks less as a result. ICE cars can't do that because their engines work best in a fairly narrow range of RPMs. But electric has no such limit.
The point being that having fewer parts in and of itself does not mean that it will break down less frequently.
I have an old 80's Toyota truck that I just can't part with. It wasen't over engineered, nor complicated. Just a vechicle I can work on, if needed? It starts, and goes. I've worked on it in the middle of s desert, with a chesp socket set.
If Tesla's do break down infrequently, they should include that in the advertising. Even though I used to be a mechanic, and a electrician the vechicle looks daunting on a mechanical level. It doesn't help that the company, like all automotive companies, don't want their customers working on their vechicle.
(Tesla has so much potential, but it needs a calm, cool, practical commander. I feel, with the right management, Tesla could become the model A of this generation?)
