If this was a planned economy I would agree and vote in the next party meeting to put chargers in every parking lot and power them with transparent PV over the parking spaces.

But since I live in a capitalist country I can't make other people invest tens of thousands of dollars just because it makes more sense than putting solar panels on my car. I mean, in some cases I still can, but there's a significant market for the people that can't effect such a change and have to make due with the less efficient solar powered car.
