Efficiency of road embedded inductive charging systems isn't even the big issue that precludes it's consideration. The hardware is massively material intensive. building out massive coils into every highway at a capacity to keep big trucks nominally charged is another fantasy concept that can't happen.
Even fixed inductive charge stations for autonomous cabs and busses are of limited value because the charge rates are limited to whatever massive, heavy, and expensive, size of a coil that you feel like dragging around in the car. Electric busses will be much better to have the operator just step out to plug in for a few minuted while people get on and off. And if you want a a high tech solution for charging an roving autonomous fleet, I would recommend developing a standardized contact plate system that would reach up and touch the matching plates on the underside of the vehicle after sliding covers are retracted.
In large cities where travel areas are dense it will be a long time before even this makes more sense than just having human attendants running up and down at large charging lots, plugging and unplugging vehicles to keep them charged.
Overnight inducutive charging systems in a home garage for people that are too lazy to plug in might find a few takers. But thinking that we are going to run heavy transport on inductive highways is , again, impossible.
