I did that a few weeks ago. We dropped our daughter off at her clarinet lesson, and intended to drive to the bike shop from there while we waited for her to get done to get my new helmet. I happened to be in the driver's seat, which is unusual because my husband doesn't like me to drive anymore since I tend to drive like I'm riding a bicycle: slow. Finally he said "Where in the world are you going?" because I was taking the route I'd have taken on a bicycle, winding through side streets with lots of stop lights and avoiding the major arterial that was close by.
Fortunately I'm not the type of cyclist who rides on sidewalks!
