Fuel Comparison Price

Your Fuel Comparison Price can be set by tapping the ··· menu on the top right of your profile and then tapping Settings & Preferences. 

This value is used in conjunction with the Fuel Economy Comparison value (set from the same screen) to estimate your fuel savings compared to driving an internal combustion engine (ICE) vehicle.

The estimated savings are shown on your stats screen as well as on drive detail screens.
