It may be that new pure ICE cars will be banned from 2025, but PHEVS have a few more years on top of tgat IF the government keeps to their ridiculous timeline.
plus, there are literally millions of ICE cars which will carry on much longer than even 2030.
add to that hydrogen is coming on stream, plus other new systems being worked upon.
for short journeys, BEVs are good (if you ignore the residual environmental effects such as power stations, rare metals use etc, the damaged caused to motorways and roads by increasing the GVW of average vars, the cost of repairs to motorways when BEVs catch fire)
but. Until you can get the same mileage out of a BEV as an ICE car I.e. at around 5-0 miles people who carry out longer journeys will stick to ice cars as long as possible.
the future of personal transportation is yet to be mapped out, electric has been a knee jerk reaction.
