The range in an EV is impacted by more variables than a gasoline vehicle. I’ve seen so many sensationalized headlines the last couple a weeks, in particular one about how the heat wave is killing electric cars.
Look, as with any big change, people have to learn how the new thing works and that takes time. I don’t get the same range on a 95 degree day as I do on a 75. The rain impacts it, charging my phones impacts it, running the AC impacts it. I believe the number provided in the vehicle is fairly accurate and considers a handful of factors. But others like your driving style also have a huge impact and there is no way to account for that.
Can the software get better and incorporate more variables in its estimate? Yes. Do consumers also just assume the number displayed is perfect? Also yes.
We had this same problem when GPS navigation became available. There were stories of people who followed the guidance before their common sense and ended up in strange places. Now we know to use it as a guide and check for common sense.
