I wholeheartedly disagree with this. I have a Model 3 and use it as my daily driver but have also done at least 4 cross country trips, two of which were in summer, one in spring, and one in winter.

For daily driving I can absolutely tell a difference in my range in the winter time and I do have a charger at home and car set to precondition. Preconditioning does make a big difference but it doesn’t completely offset the cold. Furthermore when it’s time to drive home from work I either have to drive on a cold battery or try to precondition without a charger.

During the recent cold snap (single digit Fahrenheit temps) I did an experiment with this where I started trying to precondition two hours before I left work. I just wanted to see how much battery it would take to precondition and ultimately test if that would be better than driving home cold. After two hours the battery was still not preconditioned sufficiently and I had used 20% of my battery. I would definitely have been better to just drive on a cold battery.

On long distance drives I have also found that the range suffers noticeably during winter weather. On my cross country winter trip it seemed like had about 15-20% less range between charges. And since I was driving all day and supercharging, the battery was fully conditioned the whole time. Didn’t prevent decreased range in the cold though.
