Hello all. Leaf driver here. Here’s the scenario. In hot weather if we just have to run into a store or whatever, with the leaf we just leave it running. AC on etc. As soon as I am 10 feet away with the fob the car is disabled. I close the door, push the door button, it locks and 10 feet later the car is disabked allowing me to leave the AC on so when I come back it’s still nice and cool inside. I don’t think there is a fob for the Tesla. How does one manage this. For that matter can someone get a little detailed on how the whole smartphone thing works on a model 3. Thanks in advance.
