IMO, any competent manufacturer could do it.Oaktree what evidence do you offer that "traditional" automakers know how to an EV that will last 15+ years ?
Doing it at a mass-market cost.... that's harder.
I want less tech in vehicles (DreamerDave hallucinating again.....), for a few reasons. All else equal, Less Complexity drives Longevity, and as a bonus, its little-brother - UpTime....
On a relatively simple high-volume EV, the short and long term wear items (brakes, bearings) could be covered by the aftermarket, and also the critical battery pack.
Thin-odds for my perfect EV world though..... lots of reasons to add cost; not all are manufacturer controlled unfortunately.
Today..... Software...... Sadly, I can think of a few major vectors that may well create a future EV market that will be hard to distinguish (product-cycle wise) from the cell-phone market.
