The driven distance is really off. After comparing it with the "Garage to Garage" scenarios, your calculations end up giving 1.5x to 2x more kilometers than they should. At low speeds the calculations are even weirder, the kilometers driven goes up too fast.
I tried a different mod to compare (Endurance HUD 0.31) that also adds driven distance as a statistic, and it was 99% close to the estimated distance from "Garage to Garage". So I recommend taking a look into that mod regarding driven distance.
