Not a lot more but some more. My Renault Grand Scenic used to cost me about £300 per year to insure. The same level of insurance for an ID4 would be £530 a year. To be fair, the Scenic was worth £15k when new, whereas the ID4 was worth £50k, so some of it is definitely the price.
Tesla are in the top insurance group. Apparently this is due to their manufacturing making it difficult to do things like repair minor dents, and also the tendency of people to test out the huge amount of acceleration you get, without autopilot being switched on to stop them crashing.
No. However many manufacturers will say that your warranty is void if you try to drive it like a boat (which you can do for short distances). EVs manage fords and floods far better than ICE cars. You cannot flood them like you can an exhaust.
