The range at current is far from ideal for those who need their cars for regular motorway cruising. But it's only a matter of time:
It shows what is possible when state-of-the-art lightweight materials, a slippery body design, advanced battery technology, an F1-inspired electric motor setup, and aerodynamic tires are combined into the one vehicle.

With regards cost, at current there's polarisation in the market, with private buyers finding EVs unaffordable, while those who can get one on a business lease find them ridiculously cheap (I am in the latter camp).
And, you need to add three factors to the cost: very cheap 'fuel' (electricity), no VED, and hardly any servicing and maintenance costs. So running costs are far lower than ICE cars.
But the obvious Catch 22 here is that the low running costs only offset the high initial buying price (for private owners) if you're doing a lot of miles annually.... but EVs are not ideal for regular motorway cruising....
