Yeah, you just summed it up pretty well. In reality, my gas car varies from ~34 mpg to ~26 MPG depending upon its driving profile. That is ~30% variance. Everything that I have seen of the Model 3 indicates similar variance on your "25 miles left" scenario. The causes are different (eg, the Model 3 will not be affected by city driving to the same degree as a typical gas car), but the quantity of variation is very similar.
Of course, in reality my gas car stops reporting a miles remaining # when it gets to ~20 miles, for these reasons as well. It turns out that my experience with gas cars is that its based on a non-complicated model that may be way off in accuracy with some warning. :) Interestingly, it also declines in nonlinear and unexpected ways sometimes, though I haven't correlated it to weather.
- perl4ever 8y agoYou start by endorsing my comment, but my point was how different batteries are from gas. Upside variation is not equivalent to downside variation. It seems to me like sophistry to say, well, it's tolerable for a battery to have 30% unexpected downside because a gas car has 30% upside when you go on the interstate (which would never be a surprise anyway). If I have a car that gets 26 mpg in "city" driving, then I feel secure that it will not get significantly less at the worst possible moment, unless there is a major engine problem.
- jsight 8y agoI don't understand this "upside" variation vs "downside" variation. It seems like the same thing to me. My gas car gets stuck in traffic sometimes and will vary regardless of the roads. In fact, that variance described was on the exact same commute, due to differences in time of day, traffic, and weather. Often it gets over 30, sometimes well under it. It really isn't so different from electrics in practical terms.
