Yeah I think that Tesla of all the EV makers uses the most optimistic EPA range for ads and display.

I got 260mi range max on my 310mi rated car. If it was winter or a road trip in which I could truly go fast, it easily got below 200mi.

For a 310mi car, going to visit my parents or in-laws only 75mi away for Christmas should not have made me worry about making the round trip on one charge, but it frequently drained the battery below 20 or even 10%.
