With today's assumptions, sure. Who's to say some material scientist with a trickle of funding doesn't find a way to mix in some cheap leftover metal into an asphalt mix and wouldyalookathat, for some reason you can now plus a USB cable into the road and it'll charge your phone. I'm being silly, but my point is exactly that: we just assume it won't work because yea duh, it won't work if we don't investigate it beyond "huh, if you put a car on a solar panel, it breaks. This is impossible, clearly."
