Snow yes but cold, Not so much. I grew up in Tahoe (was born in Reno). And lived there through undergrad. 17 years in South lake and 7 years in Truckee. I left in the mid 1990s for professional school and then another 3 winters. “Really Cold” there was in the teens (F) And most winters it never got below 0 (F).Common misconception. California is huge and has a diverse climate. For instance the pass on I80 between the Sparks, NV Gigafactory and the Fremont factory has more average snowfall than most parts of Michigan.
Agree about speed (EPA average test speed is around 55 MPH) and cabin heat. EV's (all of them) don't have enough waste heat to adequately heat the cabin, so must use battery energy for that if demanded.
We’ve been in Alaska for over 10 years and I’m pretty sure Tesla did much of their cold weather testing up here. I never saw any model 3’s But there were a few winters a while back where we would see fleets of S or X cruzing around in the winter.
And Donner pass on I 80 gets more average snowfall and most parts of the Rockies, and if you look at the last 20 years some of the highest snowfall of any inhabited regions in the world. The winter of 99-2000 we broke the 100’ (yes feet) at sugar bowl.
