Yes, of course you're correct. I should have been more clear and said that I believe that the sale of ICE cars will probably not be banned in 2030 and, for that matter, the sale of hybrids will not be banned in 2035.
Putting it another way, most motorists in this country will not want to buy EVs beyond 2030 for the several reasons given, especially those whose needs extend beyond driving only locally.
I'm sure that EVs, even with seven years of possible improvement, will still not have the range needed by many. Neither will people want to replace them after 4 or 5 years because the battery is becoming too weak, especially in the winter, when their used value has dropped enormously and purchase prices are so high.
Do you really think that the electricity supply network, and its generation of course, will have improved sufficiently in seven years that there will be an adequate supply for millions of motorists throughout the country to charge their cars all at once?
No good arguing, of course, but we'll have to wait and see who was right!
