Even this is a massive over-simplification. Driving the same speed with a 20 mph headwind is going to take lot more energy than with a 20 mph tailwind for example. There's lots of other variables and they may be certainly tracking some (like A/C current draw) but I doubt they track others (like rolling friction or road conditions).
Edit: I found this article [1] and it claims they track an impressive amount of weather and traffic data for the calculation. I'd be curious if this is based on car sensors (probably not?) or local weather stations.

- johntiger1 3y agoDoes all this somehow not apply to ICE vehicles? Cause the gas meter/range estimate was pretty accurate in my dad's '93 Corolla...
- bumby 3y agoOf course. YMMV (literally), I suppose. My ICE Nissan seems highly variable while my SO's Ford seems pretty accurate. Maybe it's just the difference in driving habits :-)
- LegitShady 3y agoThe mileage you and your dad got was probably pretty significantly different based on driving style, location etc. Just accelerating quickly off stops can end up having a noticeable effect on overall mileage. You were just willing to accept a much less accurate and imprecise number as “pretty accurate” and when the fuel went down too much you filled it anyways. I’ve never driven a car to empty ever. I wouldn’t with a Tesla either.
