It has always been a thing, but it still means losses and expenses to build it. If you could have solar panels in the road, you could charge electric cars directly and efficently. But like I said, unlikely to happen.
It is just that they are too expensive to make much sense. With many potential new solar tech that is in the pipeline, that might change.
