What about builders, Ford are producing electric Transits but they won't tow a 2 tonne digger on a trailer. I did read an article where someone towed a caravan behind a full electric vehicle (sorry can't remember what vehicle) and only got 54 miles per charge. So what provision is there for when ICE is banned ?
I can see the roads being full of older vehicles and the prices of secondhand ICE cars will rocket.
Modern cars are very reliable. rust proofing is much better so they can keep on the roads much longer these days. My 120,000mile 20 yr old Corsa have just scraped through another MOT for £200. It still has rust free bodywork.
If they can get 20 years out Tow vehicles and Transits, we're going to be well into 2050 before we see any significant reduction. By that time, synthetic fuels will be affordable and the ICE engine will be back in favour......
