Being able to charge your EV as you drive is just around the corner.
Check out this link about wireless power transmission up to 30 feet.

At a power of 1 watt at 30 feet,transmitters could be embedded in the interstates to charge vehicles as the pass over them.I am sure that further development will improve the range and power.
I visualize a small trench cut down the center or each lane, with embedded transmitters, with periodic branches to the sides for power source.
A debit from your account could be made automatically according to how much energy you required.This would encourage the further development of more efficient EV's and on board charging systems.
The need for large batteries would be eliminated for long trips,and they are already sufficient for local trips.
A lot of infrastructure would be required,but that would be good for a sagging economy,and put people back to work at all skill levels.
Sounds too good to be true,so I figure the Gov'mt or Big Oil will find a way to ruin it.
