I wouldn't plan on driving home, even if your car survives the initial quake damage. The next time you commute, count the number of overpasses, underpasses, culverts, etc. that you pass. Then consider the likelihood of pavement breaks, collapses and upheavals, abandoned cars, debris in roadways, etc, that is likely to occur.

Is it possible possible for you to stash a cheap, used mountain bike at work, and use that to get home? Is there a friend's or co-worker's home nearby, and would they allow you to store a few essentials and stay there if necessary? Maybe you could pitch your employer to allow you to develop a Company Emergency Preparedness Plan, so you could make better arrangements for not only yourself but the whole team?
