Heat is free when we're out driving around. Internal combustion engines generate more heat than they know what to do with. I do like your idea of putting solar panels on a car to run the aircon, though: That sounds neat!

I thought you were talking about air conditioning in buildings. In warm climates, in a car, cooling is usually free: roll down your window and catch something called a "breeze". Works great unless you're on the freeway. But if everyone moved to a warm climate, as you, suggested we'd be living way more dense so you'd drive way less anyway. checkmate
There are also these things called "electric vehicles" that you can charge with solar power without requiring a panel on the vehicle.

You're welcome! Normally I don't care what people do. But this idling cars affects everyone's air quality.
