If that stays current it will kill the leckky car market. My neighbour has just got a Tesla - will try find out what he's paying insurance-wise compared to his VW T-Cross when I next see him.
But yes, insurance has risen dramatically. Cars are complex and varied so repair is expensive.
My VW Transporter is a base vehicle with the basic black matt-plastic front grille/bumper assembly, but built within it there's a radar anti-crash sensor which is £2k alone to replace even though the bumper is the cheapest stock part....I bloody hope the sensor works!
What I've also learnt from the Transporter fraternity is that a very large number of people keep them running in very good nick over 200k miles. The basic running gear is strong and adaptable and mostly easy to fix for the average enthusiast. I can also foresee a change in ownership mentality of cars such that there will be a growing market of garages/specialists for more basic vehicles that exhibit decent longevity and are readily fixable. People will value longer car ownership and therefore reliability and fixability over bling, 0-60 times and other nonsense.
If the insurance industry reflected the fixability costs of vehicles/brands that might also shift ownership towards simple and reliable and lower premiums.
