I think it’s a disingenuous to use this argument. Even if you drive at 25mph on a flat road on a day with moderate temperatures and no wind, Tesla’s range drops quite a lot more than a mile for every mile driven. Like yeah, if you’re using air conditioning and driving at 70 mph, it makes sense your range will drop more. The problem is that they’re pretending under ideal conditions, you can achieve that max range, but ideal conditions would literally require you to turn its computer off, which would not be possible to do as a consumer.

In my experience, a Tesla driven at 30km/h will exceed its EPA range by about 20%.

data from 3300 drivers from the very article we are discussing disagrees with your single anecdote.

It's not an anecdote, it's physics.

EPA created a repeatable test where the car runs at a certain speeds, most likely without wind resistance.

If you drive faster, the car will use more energy per mile therefore will have lower range than the EPA estimate.

If you drive slower, they car will use less energy per mile therefore will have higher range than the EPA estimate.

If there's head or side wind, the car will use more energy => lower range.

Someone drove Model 3 for 606 miles, at extremely low speeds: https://www.theverge.com/2018/5/29/17405906/tesla-model-3-hy...

And yet, data from 3300 drivers disagrees with your physics. What’s more likely: the data is wrong or the model is flawed?

[bryanlarsen]

3300 drivers did 30km/h tests?

[bryanlarsen]

Are you looking at a different article? In my reading of the linked article there are three anecdotes of ~200 mile trips, most assuredly not done at 30km/h.

You're talking about hypermiling, and that isn't the condition under which the Tesla EPA ratings are achieved. I have done hypermiling from time to time (and Tesla's navigation will request you do it if your range runs low) and you can indeed get better results than the EPA rated figure.
