I'm saying that this problem is innate to any and all electric vehicles with today's level of technology. And Elon Musk is a fucking liar for trying to suggest that "battery fuel gauges" can reliably determine the "last ounce" of charge.

The honest thing to do for EV proponents is to make sure people know the tradeoffs, so that no one tries to go down to 0% charge unless they absolutely have to. Or maybe for us all to encourage battery-chargers for cars to discharge the battery fully on some occasions (to reliably figure out the zero-point calibration). I dunno what the best solution is, but liars spreading lies about how EVs work is bad for everyone.

The consumer is obviously being misled by Tesla (and Elon Musk) on this matter. And that's before the shitty range-estimates come into play (literally a conspiracy where Tesla employees have documents that prove that they know about how bad some of these range estimates are, but are working to prevent the public from knowing about it). Some of it is understandable given the difficulty of the problem of battery-estimation. But its always wrong for the company to take an official stance to lie to their customers.

Require a class before they can buy an electric car?

Tesla has temperature sensors. They could give estimated range at the start of a charge based on current conditions. It was only a few hours between supercharging stations. The temperature didn't change dramatically between 11pm and 2 am.

But they don't do that for marketing. People would be returning their new Tesla's bought in the winter when they started it for the first time and it said 150 mile range instead of 250.
