I'm in Livermore, so not as far out as Tracy, but depending on traffic, the one-way commute can be 1 hour 45 minutes (best case) up to 4 hours (worst-case Friday 4:00PM before a holiday weekend). Usual case is a little over 2 hours each way. The real soul killer is the unpredictability of it all. Every morning there's at least one jackass on each interstate highway leg that manages to crash their car into something, slowing everything down in a random, unpredictable way.
