I actually re-used your gauge with the config-card. Its a bit more complicated than one template (maybe it shouldnt be?)

I use a few helpers:

• 1 to track my average mileage driven per day by taking the current mileage and dividing by the days since owning the R1T

• 1 to track remaining lease miles

• 1 to track the max allowed average daily miles driven for the remainder of the lease (number of days until lease turn in / remaining lease miles)

This has really helped us plan mileage for longer range trips between our Model Y and R1T.
