Not disagreeing in any way for the cause of the multiple vehicle crash.

As for the top yes 100% accurate. The issue is that as roads become objectively less crowded (what they are designed for!) people are willing to move into the areas that are connected because they have a shorter commute time.

There is a reason that NoVA is soooo terrible (same with LA). Mass transit would solve the problem, period, but that is aside.

People not following the passing lane laws is one of the most infuriating things possible to me. I ALWAYS assume the person behind me wants to go 100mph faster than I am going, if I am in the passing lane. I obviously don't cut off of the through lane or on/off lane, but I definitely avoid camping in the left lane as much as possible, when it is safe.
