Never done the full commute by car as I cut through a couple places and make a completely illegal left turn on my bike. However, my normal drive is 35-45 minutes. Cycle commute is about 55 minutes. With a great tailwind, I made it home once in 45 minutes including time to educate a driver who shook his fist at me as he passed with horn blaring. The point was made that I'm legal on the road and it ended with a handshake.
