While LOS isn’t a perfect metric, vehicle miles traveled isn’t a good metric either. A slow slow trip of 1 mile in a car going only 5 miles an hour due to traffic slowdowns is bad for the driver and bad for the environment as compared to that same trip at a faster speed.

For tracking car data, the most direct should just be time spent in a vehicle. The video even admits this at 4:50 and then shifts gears to VMT which is really more of a density metric (how close you are to your destination) then how efficiently you get there.
