This is the gist of what articles in the media are saying. In theory, they could check/fix any alignment, but unless they can test/guarantee the battery’s integrity, then there is a perceived risk that the EV may eg cause a fire due to a battery issue. I guess you can’t blame the insurance company for writing the car off if the repairer assesses the car as not economically repairable.
My car appeared to be an example of this process in action. The front part of the chassis may have been bent, but the car still drove absolutely fine, so I’m assuming it wasn’t severe. (Don’t know enough about cars to say whether driving ok is a realistic measure of chassis damage).
The repairer was assessing the car. I spoke to them at a couple of points; initially, it was them that mentioned they had cars “waiting months” for parts, then at a follow-up they said that the estimate was running “over £30k”. That was about a week before the insurance company declared it a write-off. I don’t think the insurance company any ulterior motive. I think the car was later auctioned.
The issue appears to be the repairability of the car. Unless I very much missed the underlying damage, £30k to repair the car is ridiculous, and inability to supply parts in good time just exacerbates the problem.
