Tesla exaggerated EV range so much that drivers thought cars were broken

Cold climates also prevent any sort of absolute positioning awareness based autonomous driving since in winter the road lane positions are emergent and more of a function of human flocking than the underlying obscured road markings or edges.
>Other data cited by Reuters found that Tesla cars "almost always calculated that they could travel more than 90 percent of their advertised EPA range estimates regardless of external temperatures."
All EVs encounter cold weather, but most of them pretty much hit their range ratings regardless. Why should Tesla be different?
At first this felt like typical marketing BS. But I also find my inner engineer defending it a bit - the range depends significantly on top speed and head/tail wind. If I slow down to 60 mph on the interstate I have exceeded the stated EPA mileage.
I get the confusion and frustration, but at the same time the claimed range is under ideal conditions, just like every other manufacturer. But because the Tesla is so much more energy efficient, deviations feel magnified.
My experience is that real world usage gets me about 85% of the advertised range for most of the year. I average around 160 Wh/km for the driving I do, so with a pack capacity of 75 kWh, that's about 470 km. Advertised range here in the EU was 530 km.
No, not like every other manufacturer:
I’ve been asked to build tools that round up or down wherever possible, to just add a little polish to how the data is presented. But nothing like this. It definitely makes me weary about future where everything runs on software.
Seems we should default to assuming it lies until otherwise proven.
It’s not the software. Everyone is lying.
Coasting to upcoming red lights/stop signs and accelerating at a gentler pace make a big difference, as well as driving the speed limit on the highway.
Let’s not normalize amount of deception Tesla does in their marketing and user hostile behaviors.
The sort of alleged malfeasance is not normal. Edmund's claims most EVs meet or exceed their range estimates, while Tesla systematically inflates range estimates by a third.
When the missus drives the car and then fills up the tank I see range X. When I drive the car and fill up I see range Y. Different driving styles.
