The car (about 10 minutes to work) is out because ... cars suck. In many head to head races, my bike beats the bus. Add the fact that I have to leave 30 minutes early by bus, and arrive at work 30 mionutes early, the 15-20 minute bike ride is even better. Also, the bus doesn't even run when I get out of work. I would have to wait about 7 hours for the next morning bus!
