I think that idea will first be implemented with autonomous tractor/trailers. They will platoon to save fuel economy by closely following each other. That will then be adopted by passenger vehicles. Who knows if we ever go the final step and physically connect. I kinda doubt it since you can get most of the benefit of improved aerodynamics by a close follow, and there's little to be gained by putting the tow on 1 vehicle instead of distributing over many vehicles when they are all electric.

By utilizing a close draft, perhaps EV range would be doubled.
