Here's a question for the Tesla family: snowy day, 32° F out, expecting 3-5 inches, at work for 8 hours with no covered parking. I leave with 100% and get to work with 80% SOC. Do I : 1. Leave the always on climate at 65 or so to prevent build up of snow on the windows and keep the car conditioned all day, or 2. Start the preconditioning an hour or so before and maybe still have a partially covered car when I get out? What do you all do? My experience will all day climate in 30-35° F weather is I only get 2-3% an hour loss of charge leaving me with 50% battery to drive 50 miles home. Is it bad for the vehicle to do this once and a while in winter conditions, or is this what always on was made for?
