Wind makes for significant impacts, even on good cars. Let alone cars built so shittily that they shake apart on highways and leak when it rains.

The MPG ratings for ICE vehicles are a god damned mess on their own. There are lots of write ups out there but it is worth looking up the "golf ball car" video from Mythbusters (or just interviews with Adam Savage on Norm and Will Smith's Tested). Your mood generally makes for massive variance. It is just that people tend to not really focus as much on a car they refuel once a week or once a month.

But, because of regulations, those are still incredibly valuable numbers. Maybe you aren't getting 40 MPG city. but you ARE getting "about 33% better" fuel economy than a car with 30 MPG city.

Whereas tesla kind of just fucks around and then relies on gaslighting, fraud, and cultists. As is their way

The batteries prioritize keeping themselves warm. I’ve driven my Tesla down to -40. The range is decreased and phantom drain is increased, but it always starts at the end of the day, even when ICE cars all over my work parking lot don’t. I suppose it could be an issue for someone who isn’t mindful of the charge levels or who doesn’t have access to daily charging.

You probably have to use a portion of that energy to manage optimal thermal range.
