Every year, some TV station or other tries to fry eggs on the Phoenix pavement. Never works, doesn’t even get up to poaching temps. In the auto version, they could have improved their chances by putting a modest bit of insulation under the tray and (probably a cheat) tinfoil on all of the windows but the front.
Or, of course, they could have used pets or children. That would have worked, people do it all the time.
