Most people simply don't drive that way, at least around here. And it's performed in great if not ideal conditions. Up to this point, it's not lying. But we need to understand what kind of impact it has. Consider that turning air-conditioning on in a conventional car can prevent engine from stopping when stationary (because it has a belt-driven compressor) which would have significant impact on test results. But it has such a range and refuels so fast that it's not really a consideration. They leave it off for the test and nobody really cares as the fuel consumption is normal, just not as good as the test suggests. What does annoy me is fuel tanks getting smaller to save weight of all things. I have no clue how much energy the air-conditioning takes. And in winter, heat comes for free. But in an electric car, it can really add up and significantly reduce range. Just consider the effect of rims. Never before have I considered it, I just chose what looks good. You need range to be careless about such things. :-) And air-source heat pumps are not awesome when temperatures drop significantly below zero. That's why you use a ground-source pump in a house.
Yeah, buyers need to take account these things into the equation as well + the manufacturers are simply lying about the range.

Given that AC, heating and electronics are all powered by the battery, enabling or disabling these has a significant effect. A standard for testing EV needs to be developed to ensure a level playing field and that consumers understand the limits of the test results and legislation can be put in place to protect consumers.
