That's 30 hours of actual driving. An electric semi can spend 22 hours a day on the road. Realistically, you won't get much more than that from a diesel, even with two drivers. A diesel might save 5% of the travel time, but if there's mountains, they'll lose much of that. How many loads are so time sensitive that a hour or two would be worth 4 figures?
