My commute is 0 miles.
I work remotely out of my house which is one reason why I can work out for an hour at lunchtime.
Riding to the office from my house is a 40+ mile round trip to midtown some of which are on streets where you can be sure that every driver is out to run you over.
It not only saves me a fortune in gas but it also saves me about $200 a month for parking plus a couple of hours of travel time every day.
