> per hour both encourage driving more. That doesn't make sense. Whether you delivered one load or two loads in 12 hours, you get paid the same. In addition, it incentivizes the idiots at load and unload to do their job as the trucker doesn't care if he sits as he gets paid the same. "Per hour" is really the only thing that aligns the truck drivers with overall safety. You still need these kinds of trackers as the trucking companies will then be incentivized to give drivers 12 hours to drive 2500 miles, but at least you won't have the truckers trying to subvert them, as well.
