According to traffic engineers, chronic backups are caused by drivers.
"Anywhere from a quarter to half of the congestion we suffer through is our own fault.We run out of gas. We butt into merge lines. We slam into each other. When trouble strikes someone else, we slow down and gawk.Traffic engineers call the ensuing backups "nonrecurring" congestion.

They strike anywhere at any time, with the power to turn a barely tolerable -- but at least predictable -- drive into a full-blown mess."
