The headline is based entirely on the two graphs in the center of the article, which show that in most temperatures, observed range in Tesla S/Y is only 50-60% of the dashboard estimate. 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.
