Tesla has done a lot of scummy shit and they have likely outrightly lied about their range but pretty much all vehicle manufacturers do to some point.

Fuel efficiency is measured in both highway and whatever cool term the company likes such as ‘city, urban, commute’

They do these tests on test tracks, windows up, no AC, no quick acceleration or braking etc and THEN they combine them and spit out an average of the two numbers and tell you to expect that fuel economy.

It does not happen and I’ve heard of multiple court cases against manufacturers alledging they’ve lied and the fuel efficiency they state is impossible. I don’t think any large manufacturers have lost however.

Anyway, point being - range is usually exaggerated quiet a bit. It may be about to get those numbers in a completely unrealistic scenario but actually obtaining them in the real world, in traffic etc - they are all liars.
