Wind speed indicator so you know if you can take advantage of the wind, or if you are driving in the wrong place in a wake.
Current wind conditions along your route. may be better going clockwise around Indy today rather than counter clockwise.
A red, yellow and green led on the back of the car, to tell the driver behind if you are accelerating, coasting or engine braking.
Ditto, cruise control options for economy acceleration and cruise, with/out trans down shifting or unlocking.
