Some of the older trucks had those. But they are almost useless on a condensed metro route because the truck doesn't go far or fast enough to exchange the interior air. There's venting (holes) already in the top of the trucks. A solar powered fan wouldn't drain the battery and would run the whole day if equipped with a thermostat to turn it on at say 70°friend or above and shut off when the cargo area drops to the desired temp.A few simple fold out vents would work wonders. Two up front that catch and allow air in, two in the rear that exhaust the heat. As you drive, the air flow increases. Probably $50 a truck. Small price for a huge safety issue.
Maybe the drone can circle you back a cold drink and run it's rotor blades to cool you off.
