The real point is two cars
My Diesel-powered Volvo wagon gets 26 mpg in stop-and-go traffic and 34 mpg in mountain driving. When I vacation, I can drive for up to 500 miles between fillups, while driving with the air conditioner and stereo on. Make an electric that can do that, and which is cost-competitive with a straight diesel system, and I might consider it as a replacement. I definitely won't be interested in having two cars, one for when I need air conditioning and need to drive a long distance or carrying a large load, and one car for short hops. The very wealthy can afford that; I cannot. As they are now, EV's are no competition at all for a good car with plenty of power, hauling capacity, and range.
Perhaps, some day, someone will have the sense to make an electric car with the range and capacity. If it does, it'll probably be a diesel-electric system, whereby the energy comes from a diesel motor and electricity drives a motor in each wheel. Call it a plug-in hybrid, if you wish, but, because of the fire risk with modern gasoline, I would not have it unless the liquid fuel is safe, dependable diesel fuel.
