Gravity 75 mph Range

If you’re THAT out of it that you buy an EV and do zero research about it, that’s on you. IMHO. Also, ICE cars rarely get their EPA estimate. IDK. I have little sympathy for folks who are like “I had no idea” when such and such happens with an EV. Or any car or major purchase.
Then it will continue to give EVs a bad rep because as much as trusting the government may be antithetical to you and I, many people *do* trust the government and expect their data to be reasonably accurate. Which it's not with current EPA range in the way most people care about it (road trips at highway speeds).

And really, regardless of how much it should or shouldn't be trusted, there's no reason not to want it to be reasonably accurate.

I generally found EPA MPG to be reasonably accurate on ICE vehicles. Not that it mattered as much on ICE because being a little off usually just means costing a bit more in fuel, not stranding you 30 miles short of the next DCFC. But still, I found MPG to be reasonably accurate in my previous vehicles. Far more than EV range, anyway.
 
You do know the EPA methodology is based on input from "interested parties". This includes the car makers. Back in the early 2010's (2010-2014) the car makers preferred that efficiency be reported in MPGe. To provide a comparison to ICE vehicles.

Tesla wanted EVs to be shown with a w-hr/mile. Some advocates wanted ICE vehicles to be reported as gallons/100 miles to better emphasize the differences between high fuel economy cars. EPA added kw-hr/100 miles and gallons/100 miles to their published data based on these comments.

Fuel economy has rested with EPA (with input from DOE) since ICE cars economy is calculated by measuring the CO2, CO and HC in the exhaust.
