I make the 4S to UCSD area commute daily. It’s sort of annoying but not that bad. (Usually about 40 minutes if leaving at 7:45 am).
But yesterday (12/11/12) was atrocious (almost 1.5 hrs), thanks to the major accident on 15S causing thousands of people to try to cut thru Camino del Norte down thru RPQ to get past it.
