Tesla App - what do the Red/Blue arcs around mph mean?

[roser]

While my X is at the SC, I can't help but track via the Tesla app.
Anyone know what the blue/red arcs around the mph graphic mean? They change in size as the car is driving around.

Speed and power/throttle. If you are a new owner this is also depicted on your speedometer in the same colors.

It's made to resemble the original speedometer that only exists on pre-Autopilot Model S now. Blue is speed, orange is power, and green (not shown) is regen.

Is it meant to represent instantaneous values or max/cumulative for current trip? Reason I ask is that if I am using this app function to monitor someone else's use of my car, I'd like to know top speed achieved, max/cumulative energy, etc. without having to stare at the app for an extended period of time.

Instantaneous...literally what's happening at that moment. As mentioned above, it mirrors my pre-autopilot Model S dashboard.
