A couple of points, and I may well be wrong but here goes.
1. I don't remember ever having an ICE vehicle with a range of 500 Km like the BYD Atto 3 and many other EVs.
2. It's true but they will come. Just as farriers became tire fitters way back when. Most of the moving parts that are prone to breakdown are the same anyway.
3. I think that if any accident caused such frame distortion as to damage the battery, any car would be a write off.
