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

Inundated with complaints, Tesla created "Diversion Team" to cancel appointments.

Isn't the epa responsible for publishing and testing the numbers?
In the article they talk about range estimates done by car itself. So you are driving and thinking you have 50 miles, while actually only 30 miles left.
Not a Tesla fanboy but just noting EV range in general can be quite hard to predict - there's a huge drop off in efficiency at higher speeds, so driving through town I may get 350 mi range on my 300 mi rated EV6, but on the freeway at 75+ mph, I probably get less than 250.
Not surprised Tesla exaggerates their range though. YMMV.
Some people would probably complain if they had a 100mile trip up a mountain pass and it took more than 100 miles of energy.
At least when you plan a route the % indicator takes that into account vs a plain estimation.
My best trip once going up a pass was around 70km of the reading staying within 1 or 2km the entire time when going down it.
But ya there's so many variables. But if they were fudging calculations that'd be bad.
