That's really going to help with the supply issues.
Safety is one thing, but many over regulating factors are causing some serious issues in accomplishing productive level's in the industry, and this whether it's in hiring employees, training them properly, truck maintenance cost, fuel cost, tire cost, parts cost etc.......
Safety and production level's have to exist together on a fine line, but when government over reaches, and they push to far, then production begins to lose big time.
For example: The DEF system's have caused the industry more down time, and more expense that could have ever have been imagined, but no attempts to address the issue by revisiting it is ever made (just have to take the losses no matter what the cost to the industry and nation is), because once they go there they are to damned proud to ever go back.
Cutting truck's back to 65 mph over the road in which can easily accommodate them going legally 70 mph is another issue that gets straight at the heart of the disrupting of traffic flow (causing non-unity between 4-wheelers and truck's out on the highways), and in turn also causes the disruption of supply chain issues or of production within those issue's.
Having the wrong posted speed limits on road's that can easily and safely allow for a 10 mph increase is another issue that doesn't get addressed by the states, otherwise that are using or setting up speed traps for generating revenue's... When this is seen, it usually is operated by harassing unsuspecting victim's traveling through the various state's that are engaging in such method's for generating revenue's instead of focusing on safety.
If it wasn't broken, then why fix it right ? That's what has happened in many things going on in this nation. Once climb up on the rickety ole ladder, then beware of the fall that's coming.
No one is ever suggesting that safety should be sacrificed for production people, but what's gone on in recent year's has bull crap regulating written all over this stuff. It's crippling the country and it's industries, but just like anything new, it's hard to back down off of that rickety old ladder without falling after climbing to high up on it.
