DC / N. VA / Baltimore
To drive the 56 miles from my office in N. VA to Home (Baltimore) during most evening rush hours (3PM - 8PM) about 2 1/2 hours. One of the main reasons I only work at night.
Just pull over, many places to eat and relax until it dies! I move around before rush hour or after but you can hit traffic at any time in LA. Usually just go with it and hope for the best or pull over as mentioned.
