As someone who owned a car without AC for several summers, I’d say you’re incorrect on that assumption. In fact, this is something you can try in the summer time with any car with AC. After a hot day in the sun, go drive around without the AC on and just the fans on and windows down. How do you feel? Then kick on the AC (leaving the driver’s window down, stimulating running a route delivering to mailboxes.). You’re telling me there is NO difference in feel without cool air blowing at your body?
I’m not putting the calculations of how many more dinosaurs will be used to in this, I’m merely focusing on the carrier being a little more comfortable during their drive.
There is a small relief provided by blowing the cooled dehumidified air over the warm sweating body using the dash vents. This would give the person a chance for their body to better perform the evaporative cooling process even if the cabin can’t stay at a constant lower temperature. I’d argue doing something to help with the comfort of the carrier is better than a vehicle without AC - and understandable it’s worse for the environment because of the waste heat generated in the process.
Too much amperage for a circuit is fine, for a battery is not. A circuit will present a known resistance and draw what is needed for a specific voltage. The batteries’ resistance will be very low at empty and change over the course of charge, and certain chemistries can be damaged over 1C.
