There was another article posted the day before on cnbc that talked about the same thing, but more anecdotally based on individual users: https://www.cnbc.com/2019/02/05/tesla-j ... emps-.html
I agree its an issue, but I believe it really is only affecting folks who live in the coldest areas of our country that get down to below 0 Fahrenheit.
I grew up in Ohio, and even those temperatures are pretty rare. Hopefully, battery tech can improve, and people's expectations can be made appropriately when weather this cold happens.
What both articles I think fail to mention is how LITTLE power is required to run seat / steering wheel heaters. The power is so small (less than a few hundred watts combined with all other electronics / displays running) that the range hit would be less than half to 1 percent of the total range. I've seen at least a couple sources report that using seat heaters will reduce your range, which couldn't be farther from the truth.
