This is asinine for all the reasons others have already stated. The only place solar panels could make sense is on the road shoulder. Even then they need to be robust enough to handle having an 18 wheeler park on them. Or you only make them strong enough to park cars on them and replace them when 18 wheelers do need to stop on them with the savings earned from not over-engineering them to withstand 18-wheelers. That said, I do think roads are a prime place to combine with energy distribution infrastructure. On top of energy distribution, we don't need cars with batteries if they can instead function like slot cars getting their energy from the road surface below. This greatly reduces the weight of cars such that they are much cheaper to accelerate and decelerate and the stored kinetic energy is much lower making them much safer. Basically roads need a safe "automotive third rail". PG&E in California in partnership with the California DoT is the ideal company to pioneer this approach. Moving batteries around is great short term, but long term we really should be electrifying roads.
