This feels like an idea that barely made sense before widespread charging and long-running batteries that makes no sense now. How much of a charge could you realistically get at highway speeds on a ~1 mile stretch of road? Would it even out-do a solar panel placed on the dashboard while you're parked at either end of a trip? Now, inductive charging at parking lots might make sense. That could resolve a lot of the issues that are starting to crop up with charging stations that look a lot like gas pumps.
