Poor battery performance has always been what killed the electric car.

People have been trying to develop a workable battery for over a century. You see how much luck they've had.

Practical electrified surface transportation means electrifeid freight railroads and maybe electrified truck lanes on the superslab. Big trucks are approaching the power where they have to go to electric drive. About 1200 HP is about the limit for mechanical transmissions.

Once you electrify the transmission, it is ashort hop to a truck that runs of diesel locally and a catenary for long distances.
