Fair enough. :) I think you might draw a distinction, however: A former BMW (same price space as Tesla) repair tech probably has the know-how to repair future BMW models (or cars in general), because internal-combustion cars are a very mature technology (at least where there are moving parts). On the other hand a former Apple repair tech would probably have a lot less confidence in their ability to repair future iPhones and iPads, which are relatively new and rapidly-changing technologies. I think that it's very possible Teslas are more like iPhones than they are like ordinary cars. You could even make the case that electric cars are a less mature, faster-changing technology even compared to smartphones.
