The range of cars being offered these days (fully electric, not hybrid) is in the main of the order of 200-450km with prices reflecting that spread. In some countries fully electric cars are in top or second place when it comes to sales in the first half of this year. Mind you, not only do they have a fairly good spread of charging facilities in some places abroad but up to now lots of them have been fully free. I was talking to someone just in the last hour who was driving an electric car in Spain last week and a 450km range charge cost €10 from a public charge point (not a Tesla rapid station) - that is a fraction of what it would cost to cover the same distance in a small petrol or diesel car (this was a large Tesla). Regarding silence or not, Mitsubishi vehicles emit a low frequency hum/droning sound which is very distinctive, some others are silent and yet others emit their own hum or something of that sort. The UK was slow to accept motor cars and required a man on foot to precede each vehicle carrying a red flag. The UK is notoriously suspicious of any change and acceptance of electric cars will quite possibly also be slow - charging stations are around (in the UK) but not that frequently found.
