This would be the right thing to do. It would reduce rush hour congestion, maximize driver productivity, increase safety by reducing fatigue, and allow the trucker greater flexibility to maintain his/her own biorhythm.
Many's the time I've done slept all I care to but still can't drive for several hours because of the new rules, so I have to twiddle my thumbs and wait before I can log in for a pretrip inspection and get the wheels rolling. Meanwhile my biorhythm clock is ticking and I know I'll need a long break in the middle of my 14 anyway. I'd much rather be able to "run and gun" while I'm fresh off a satisfying sleep, before rush hour, then be able to finish out the balance of my 10 when my body needs it.
