The really real reason is you won't be able to do the subtle cheats anymore.....
I don't do subtle cheats, because I don't do anything subtle, lol.
As Tom said, the problem is the inability to stop the 14 hr clock, as we used to, with the split sleeper. Detention at the shipper? No problem, driver took a nap, was refreshed & ready to drive when the load was done, everyone was happy. Only the shippers don't care that we can't do that anymore - they still leave us waiting to get loaded for hours, sometimes. It happened to me awhile ago, when I notified dispatch that I couldn't deliver direct legally, they "consulted with the customer", and made me crossdock it halfway - I lost half the revenue!
When the sleeper berth was changed almost 10 years ago, drivers by the thousands told FMCSA it was wrongheaded, just as they have with the restart rule, but nothing has changed, and you know why? Because it didn't affect the carriers, and they didn't go to court or their government reps to get it changed, like they did with the restart rule.
It's just one more example of how people who make rules about working ignore the people who actually do the work, and it makes me mad. Especially when it costs me money, because this is my livelihood, and it matters to me.
Sorry - everyone can go back to the 'banter' now.
