Want to see what Pam sees every day?

Of course, limit the trucks with expert drivers but not the cars, which essentially have no top limit and drivers who for the most part, learned from a family member at 16 and have had no further training since. I see them all day long, ten to twenty mph over, changing lanes illegally, tailgating, exiting from the left lane, failing to yield the right-of-way and much more.

Big companies are behind the push for a de facto national speed limit on one class of vehicle, a la Canada because it will eliminate the competition from independent drivers who can't haul more but can do it faster than they can.

I would rather see mandatory black boxes in all cars and trucks (we already have them) but coupled to dashcam footage from the front and both sides. Then the lying and misdirections from all involved will cease and have the added benefit of cutting down on frivolous lawsuits.
