There are two more charts at the bottom: looks like both Ford and Chevrolet are overestimating in cool temperatures. But during higher ones they match EPA.

It doesn't mean anything. FTA:

"Every other automaker has a different approach to sharing those estimates, but it often tends to be closer to reality than Tesla’s approach."

It's not clear how much that information affects whether or not someone buys a Tesla vs other EVs.

Everybody advertises the EPA numbers, and that's generally what people use when buying new vehicles. This article isn't about the EPA numbers, it's about what number is displayed as the range on the dashboard. And on non-Tesla's that number varies based on driving conditions, so it'd be a poor number to base buying decisions on.
