Between stop lights and taking back roads to work, my driving commute in is 13 minutes, starting car to parking. (I could take 101, but having to come to a complete stop on an onramp makes my commute much less happy).
My biking commute is 30 minutes, getting on the bike to getting off the bike.
Biking isn't that much slower than driving! I'd never timed it before, but this is surprising - it's only twice as much time to bike!
