We solved this problem a century ago for the railways. Build trolley-style wires over the interstates. Your vehicle is directly grid-powered while on the main roads, potentially even trickle-charging, and only needs to go battery for the last few miles. This could also potentially increase order and predictability on the roads-- vehicles have to stay in lane and move only at designated turning points in order to maximize use of the grid supply. Autonomous vehicles could use the wires as an effective feeler to make sure they're staying on a defined road. Yes, it technically doesn't fix aviation, but if we can avoid solving an already solved problem, maybe it frees up some better minds to look at that. TBH, I could imagine a lot of aviation being displaced by better high-speed rail options, hopefully getting to the point where it's less of a critical emissions concern.
