I really have no idea why people have kickstands for parking. I understand the utility otherwise. In fact, I used the kickstand on my wife's bike just the other day while getting all the bikes on the car rack.

I went to a bike advocacy meeting a while back, and there was a bike next to the rack on a kickstand. It was in the way, any breeze could have knocked it over, I had to work around it to get my bike in the rack. It made no sense since this is a reasonably high-theft area and it was only locked to itself. I was really curious who at the meeting was that nuts, but was afraid to ask.

When I worked in a bike shop, it always seemed like a good idea to have a few bikes on kickstands until one of them got bumped and they all went over.
