Before I moved I was 25mi from work and it took me 2hr each way. When I started cycling I would drive to work with the bike, ride home, ride back the next morning, and drive home. And do that no more than once a month. But that's parking in the free lot at work, same as regular days.
One time on bike-to-work-day, I scheduled my car's oil change on that day and rode my bike to work like 1mi from the oil change place.
But then I moved 5.5mi away from work and there is no reason to drive partway.
One of the things I say when I occasionally get contacted by headhunters is that I won't consider any new job I can't bike to.
I have daydreamed, it would be pretty awesome to buy
one of these condos, and have a job in Mira Mesa or Sorrento Valley, so I could commute on the trail through the canyon every day. If Qualcomm ever comes at me with an unsolicited job offer, I'd really think about it.
