Until there's nuclear power to generate the smoke in the wires, and until the range is 1,000km+ I doubt they'll take off in a big way.
A "swap-n-go" battery system may go a long way to sorting this out...
But on some trips I drive to the city, do 200km and drive home - that's 1000km in a day.
No time to wait 3.5 hours for a zap!
