Why does Meter screen show 320 mph?

Why does Meter screen show 320 mph?

The speed marks on the Meter screen are  0, 20, 40, 80, 160, and 320!  Is this supposed to be a logarithmic scale?  Given real time data will be scanned very quickly by the rider, a non-linear scale is not useful.

Also, there's a lot of stuff on that screen that may not even operate...like Throttle and Engine Temp which require an optional OBD reader which isn't even available yet.  And given many bikes, especially BMW's, already have TPMS, why are any AIO-5 displays cluttered with that info?

Just say'n.
