The headline seemed implausible, so I read the article. The article title and the title here do not match. Sigh...
But in the real world, most Tesla drivers get within a reasonable error rate of the EPA rated range, and if they don't, they can understand why using the car's very detailed consumption app (e.g., driving fast, lots of quick accelerating, temperature).
Articles like this seem engineered to entice people predisposed with anti-EV or anti-Tesla bias.
The two graphs also show that Tesla pretty much uses the exact EPA estimated mileage for the dashboard estimate, regardless of temperature - it's a straight line. While the two graphs at the bottom show that the Mach-E and Bolt have much more intelligent dashboard estimates that account for temperature.
