Anyone else seen that MPH logo on the cluster?

[RazorRob2024]

Got this SE like a month ago, and noticed this MPH logo (letters ‘MPH’ with a left curve arrow above it) on the speedo in the digital cluster, bottom left. It popped up when I was in green+ mode cruising around 50mph. Anyone know what that's all about? I'm new to this SE and not really clued in on all this stuff.

AFAIK, this feature turns green when you reach your selected fuel-efficient speed range, especially when you're driving slow.
