It's not my regular way, but I go cycling several times a week, occasionally commuting but more often for recreation and sometimes to buy minor things. I'd commute more often by bike, but I'm always concerned about parking my bike on the sidewalk. I wish we had a greater number of secure parking facilities for the public like the one at Union Station. In Japan they have those mechanized underground silos for bicycles which would be nice to see here as well. There are some simpler ways we could get more secure parking, like parking lots or garages offering spaces for bicycles visible from the attendant's booth for security.
Also, on a more fantastic note, too bad they didn't design PATH to be wider. It could have allowed for great traffic-free cycling routes.
