Soaring gasoline prices are making it easier for cycling organizations in Columbus to build a case for commuting on two wheels instead of four... ...But not everyone can get to work on a bike, said Joe Fish, a planner at the Mid-Ohio Regional Planning Commission. It depends on people's experience level and whether they are comfortable riding on the street, he said. Also, most people don't want to commute longer than 15 minutes, which equates to roughly a 3-mile bike ride, he said.
UPDATE: John's comment inspired me to do a quick back of the envelope analysis. Assuming 12mph average biking speed, my round trip commute on bike would take me 2 hrs 40 minutes (16 miles each way). Driving it takes me 50 minutes. At about 24 mpg in my car and $4 per gallon gas, the driving commute costs me $5.33 in gas and 50 minutes in time. Comparing that to the bike commute time of 2 hrs 40 minutes, I have to ask myself is 1 hr 50 minutes I save by driving (and not biking) worth more than $5.33? I think the answer is obvious (but you might not).
