I would think the biggest limitations would be: - Cost of placing under the highway (mitigated by only doing so on full reconstruction/maintenance works) - Cost of materials (massive induction coils, over a very large distance to get meaningfull charging.... - Cost of electricity (Induction would be much less efficient than direct charging - rather than 100%, you'll get a fraction of that (heavily dependent on the distance from the body to the roadway - good luck Electric F150s..) Roads are designed to be as cheap as possible while fulfilling their purpose. It's difficult to imagine you could cost-effectively spread that charging infrastructure out. It would be more expensive than pantograph electric lines, which would be much more efficient at actually transferring energy. EVs are still only a few percent of all cars, so this infrastructure would be unused most of the time. Cars with inductive chargers underneath will be even less common, and people willing to pay the premium to use them less common again. This seems like a pipe dream like solar roadways, sounds good but beaten out by the normal, sensible solution of just charging at stationary car park where cars spend 95% of their time. Batteries are only getting cheaper as well, which hurts the business case too.
