The batteries in electric vehicles wont last for ever. Making those and the cars will not have a zero carbon footprint. Replacing all fuel usage with electricity needs and unbelievable amount of it. A conventional car may have a range of 300miles or more at motorway speeds. Trying to replace that with electric isn't that simple.
The higher range stuff coming out now uses lithium variant cells. Statistics are likely to suggest that most peoples usage can be covered by a range of something like 50miles at urban speeds which will include a stop start driving. Electric is good as that but not so good as heating in the winter months or cooling in the summer.
These are not guesses as I spent several years working on them. Figures will be something like that.
Gov noises about charging points suggest they do see some of the complications and may see them initially at least as a means of commuting. They are also aiming to deBeeching the railways. They know that for a variety of reasons people are likely to need to use them more.
In short - some indications that they don't see people using private vehicles that much at all. Trams etc in cities. Park and drive etc. Keeping fuelled engines out of cities reduces pollution enormously all on it's own.
Get on your bike or e scooter - see what happens when we get a rainy week and in winter.
Only good sign is hybrids with higher range and more efficient engines shortly.
Just leaves the problem of keeping warm in winter etc. Suppose they could be insulated with 250mm of rock wool with zero ventilation and triple glazed windows etc.
Anyway what ever the UK does short term we will continue importing from polluters.
