i live roughly 5 miles from work. my route takes me through dense, urban, congested, trafficy surface streets on chicago's far north side and south evanston. times are roundtrip.

car: ~45 minutes @ rush hours

bike: ~50 minutes

train: ~60-90 minutes (i have a 10 minute walk to/from the station, and an annoying line transfer that's a total crap-shoot on the timing, hence the big range)



my driving vs. biking quotient is 1.111, so i need to have a pretty compelling reason not to simply just ride my bike to work.
