This thanksgiving weekend I hit the worst traffic I have ever seen coming home on sunday. And I have done this trip every year for 8 years. And you hit it on the head, lane parity would help. I know they teach it. But you get morons that insist on traveling in the left lane, or on 3 lane highways the middle lane forcing those who want to go faster to weave in and out.
A 5 hour drive took 8 hours.
