Because ideally consumers should be allowed to make informed decisions, which is not possible if one party - willingly or not - misrepresents the numbers. Tesla should be criticized for every number they inflate. Every time they pull some marketing crap, they should be called out on it. If it's such a benefit as you write, why do they feel the need inflate the numbers? What happened to honesty among engineers? Understated performance, instead of throwing around huge numbers that are technically possible but are nothing short of misleading for the consumers? I suppose it clearly works for Tesla, but my support goes to the company who claims a conservative number that I'm actually likely to exceed in reality.

Is there evidence that they are misleading or cheating? The EPA numbers (I assume) are arrived at with the same methodology for all cars. It's indepedent right? (I have no idea). So how is Tesla at fault here, if their cars do well. Btw, you can get the EPA range if you drive around 55-60mph... So it is misleading?

  It is not independent. The EPA defines the test methodology and the manufacture conducts the test themselves. There are some loopholes that manufactures can leverage to improve their score, like offering a model without A/C, tiny tires, or tall gearrs; having a "eco" mode; or having a shift light on the dashboard. The EPA test methodology is actually pretty sound. It includes things like multiple wide-open throttle accelerations to highways speeds. The problems appear to be lack of independent testing and the existence of loopholes mentioned above. Companies like Honda seem to always beat EPA #s and Ford always seems to fall very short of the numbers.

    All those things you list as 'loopholes' aren't something Tesla is doing here, besides maybe the smaller tires (which really, aren't undersized, they're just the smallest ones they offer happen to get best range). I'm not sure what you'd expect, given that every single defined test can be gamed. 'Real world' is different for everyone. And if you drive 80mph, every single car ever will underperform compared to the stated EPA range/mpg.
