Battery charge status [estimate] way off on road trip

[Gasaraki]

That is definitely known and calculated in. That is known from the map data. As a way to see that obviously, you can plot a trip, and then look at the Trip line graph in that energy app in the car, and it shows the line of remaining energy rising and falling in the opposite directions of the uphills and downhills, just as you would expect.

I'm pretty sure that is mostly wind. My wife and I were on a trip across I-80 in Wyoming once in our Toyota Prius, and it has that instantaneous mpg gauge. It sat there pegged at 99+ mpg for a very long time, as we had a really fierce tail wind. That can make a shocking difference sometimes.

Yes, elevation changes are taken in to account but the biggest factor that throws off the estimation is WIND. I wish Tesla would just buy the Windy app company and integrate wind speed and direction in to its calculations.

Agree, wind is huge. Unfortunately around the 90 to 100km/h mark wind becomes really important. So when you cruise at like 120km/h and suddenly you have 15km/h headwind which is fairly normal you drive like its 135km/h...

Yes, that is a good one. I read that a few months ago and it had lots of nice information.
