I can see in the near future cars being bard from big towns and cities because of pollution. And the only way to get into them will be like we used to many years ago but on an electric bus. I can see electric cars being able to go in, but how many can afford an electric car.
The cost of electric cars will go down as more are produced & it becomes the 'norm'. You can buy a new electric car from £14/£15k, which is a lot less then you could a couple of years ago. As more manufacturers produce them, there will be more innovation & more competition which will drive the price down.
Not everyone needs to own a car, however, and it's already been noted that car ownership has started to decline for younger people. There has been a push to re-open train stations here in Birmingham & elsewhere, because people don't want to commute by car because of either congestion, or the fact that they don't have a car.
So yes, it might go back to more like my youth when not every household had a car & you got everywhere by public transport or taxi. I can't see a problem with that.
