Everything that doesn't work towards moving the car forward but requires electricity in an an electric vehicle lowers the range. Moving the power windows, using navigation, A/C, heat, stereo (louder is worse), heater, seats, etc. They somehow took MPG averages of "we went 55mph down the highway with no wind on a perfectly flat and straight stretch of road and got 30mpg" and ramped them up to absurdity with electric car range. And one of the worst parts is that governments let them lie about it because they'd rather let them sell "zero emission" electric cars that deceive everyone and be green.
