there are two things that prevent people from switching to an ev at the moment, the cost of the vehicles themselves and the availability of charge points.
until the government takes action on those the take up will be slower than it could be.
lesser things are the size of vehicles available and the range but range is less and less of a problem with better batteries and education of drivers about manageing journies and charging. it would also be helped if the govt got a grip on rolling out chargers.
whats wrong with insisting all new build houses have chargers built in by law.
