There's a huge market for people who want to buy superior cars though, or even cars that are simply perceived as superior like VW Audi for example.
Electric cars are a vastly superior ride and have that all important performance factor for a certain buyer. Once the neighbour effect kicks in it wont even matter if they remain a bit more expensive than the ICE equivalent.
So long as they are no worse polluters than ICE cars, they will still have the edge for a huge amount of buyers.
Then you've got the noise pollution issue once health departments get onto the science showing the damage the constant abuse of noisy ICE engines do to our ever increasingly denser way of living. Roll on Oxford's ban on ICE cars if not just for the noise.
