I also run my ICE cars at 70...

I don't know about your Rivian, but in the Y I just set it to Auto and 69F and it keeps the cabin nice and warm. The other day it was 37F, and I only used about 2 percent more battery than today, which is 50F. That was mostly because I ran the "Defrost Car" mode for 20 minutes, which turns everything up to Full, including the seat and steering wheel heaters. As far as efficiency, I still used 2 kWh both times for my 10 mile commute

Garages stay warm enough. It was 20 degrees last night and 58 degrees inside the garage when I backed out and that was with the garage opened for a minute or two while I got in, etc.
My garaged cars aren’t cold to get into to begin with, and the heat comes on almost immediately, by the time I’m at the first intersection near my house.
Parking outside, yes that’s very different. However ICE remote start is great, it’ll crank the heat or A/C.

Eh, while it’s a cool feature…

With EV's, you just set the schedule, and the car will warm the interior before you leave. I leave at 8am, so the car warms itself 15 minutes before I leave.
Todays EV's have heat pumps, which are highly efficient, so you don't lose much range in cold weather. Most can operate efficiently all the way down to -30 C (-22 F). On Monday it was 37F in San Jose, and I used the same 2 kWh for my 10 mile commute as today, which was 50F. If I look at both my summer and winter driving with temps ranging from 100F to 37F, I'm averaging about 28 kWh per 100 miles, which is well above 100 MPG

Granted it gets way colder other places, but it was 22 degrees last night which is way colder than normal this time of year and my garage was fine temp wise.

My ICE cars would spend 3x more fuel in short drives in city compared to highway longer drives, during winter periods.
I mean this is a well known fact:

Cant believe you never noticed it. What car do you drive?

Uh, really? Actually during warmup and short drives, heat in ICE will spend incredible amount of fuel to not only heat up your cabin, but also make emission equipment work properly.

An ICE car is going to heat up regardless and do all of those things you mention. The heat is just a blower blowing heat “off of the engine” like I said. It doesn’t cost any mpg, unlike a/c….and A/C is NOT EVEN CLOSE to a 20% loss either. It’s minimal.

I don’t believe anything in that article. 20% loss in MPG in cold weather? Never in my life. I’ve never noticed cold weather even ever affecting my gasoline range and I’ve been driving for 26 years. Instantly the credibility goes out the window. Plus it’s from the government, that article is complete BS.

Cars warm up, they all do and they always have. My cars nail or exceed their EPA ratings.
Using the heater has no effect on MPG.
