Oh, and I can tell you -most of the tuckers ARE slowing down, even though it's hard to meet delivery times - which is crucial.
Most places, if you don't meet your delivery slot - they can make you cool your heals from hours to days - and if you're running reefers, you have to keep them going... among other pitfalls
If slowing down does conserve fuel maybe the delivery times need to be more generous.Do you think that could happen?
