When I lived in Seattle, it was 75 minutes each way (58 mi), if traffic was good. I later moved to Philly, and it was 4.7 miles each way, which was usually about 15 minutes. Now my 'commute' is about 6 feet from bed to desk, with a detour to the kitchen to make coffee and feed the cat.
21 miles, 30-45 minutes each way in the East Bay region of the San Francisco Bay Area. I have to leave home before 6:30am to achieve a ~30 minute commute; commute conditions deteriorate after 6:30am. If I’m unlucky, though, it could be 60 minutes in stop-and-go traffic.
