I was in Pleasanton, CA yesterday charging the car and it was 101. Just 10 min before I walked to the car, I set it to cool to 64. It was indeed cool when I got it. The I stopped at a shopping center for 30min and it hit 106 outside. Again pre-cooling for 10 min did fine. My lucky day? I will take it. I did not have to tinker with the AC on/off etc. I will surely report back after a planned trip in 3 weeks all the way from CA to Montreal Canada via Bakersfiled, Vegas, Denver, Chicago and back via Detroit, Indianapolis, St Louis, Albuquerque, Kingman, AZ.
