A lot of people conflate the EPA rating with how far they can travel on a road trip. They are obviously not the same. The EPA rating uses a mix of city and highway driving and doesn’t necessarily have to account for things like altitude, temperature, cabin climate, etc. It also benefits from the use of regenerative braking which can make a significant difference in total range. It’s not a bad test per se, just limited.
I do agree that battery size and efficiency is a better metric in comparing vehicles. The reason that we often become fixated on distance is due to the distance that exists between charging stations. As chargers become more plentiful we’ll be less focused on distance traveled on a single charge.
