On the other hand, just seeing the headline I can't say I found it hard to believe - among the major car manufacturers, Tesla seems particularly prone to tweaking the performance numbers they put out. 0-60 figures measured from a rolling start instead of dead stop (that no one seems to be able to reproduce either way), hp figures that are a "peak system power" calculated by adding things up in weird ways and which can't be sustained for any length of time, range figures no one hits in the real world, ... they're very aggressive at this, and it'd be a mistake to think everyone does it this way - for example professional testers regularly exceed 0-60 figures Porsche releases officially.

I've seen a fair amount of professional testers/journalists reprimand them along the lines of "every manufacturer is guilty of this to some extent, but Tesla really ought to tone it down" (e.g. Alexander Bloch, who is generally very positive on the brand). As EV tech is commodifying swiftly and the competition closing in, I expect this to become a larger discussion.

> 0-60 figures measured from a rolling start instead of dead stop

That's pretty normal. One magazine (I don't remember if it is one of the car magazines or Consumer Reports) offers both numbers, from a true standstill and with a slightly rolling start. The latter is much more common, I believe.

Hagarty has a program with Jason Cammisa where this was recently debunked as well [0]. Many manufacturers do this.

> range figures no one hits in the real world

I was curious so I looked...

Wikipedia[0] says the energy of a gallon of gas is 33.70 kWh and MPGe is:

    (total miles driven) * (energy of one gallon of gasoline) / (total energy of all fuels consumed)

My Tesla Model 3 LR RWD has a government rating[1] of 130 MPGe, the odometer[2] reads 26,328 mi and 6,727 kWh:

    26328 * 33.7 / 6727 = 131.89 MPGe

So I'm doing better than the rated MPGe. I don't hypermile either, my partner would kindly describe my driving as aggressive.
