Smaller vehicles will likely be a lot more viable for most of us, rather than an expensive electric car.

Electric bikes, for example. Certainly on a "last few miles" basis. If you live further than that, then public transport will end up being the bulk of it.

Public transport should be heavily subsidised.

Maybe the prices of electric cars will come down to acceptable levels, but I suspect that there's a layer of people who could just about afford to keep a 10 year-old petrol banger on the road, who won't have that option under electric vehicles. Something needs to be provided and quickly.
