Agreed it is not going to happen for most businesses. My present gig has bike lockers and so I cyclocommute. Without them I would drive. The only way it is going to happen is:
A- some cities starting to require all big box stores to supply them, so something like a disabled law suit claiming discrimination
B- Lockers could be designed so they are not available to homeless,
C- something like the Japan/French, put in a credit card, put you bike in some mechanism and off it goes until you come back and retrieve it. {For those who haven't heard, the French idea is ugly, like a umbrella of bikes that are stored above ground. The Japanese idea is a huge storage unit for about 200+ bikes}

I'm not waiting for any of these solutions. I just do as roadies, forget small errand cycling, only ride for commuting or joy on the road.

I'm just moaning the lack of options. It's not expensive, it's a lot cheaper than paying a full parking lot. It's more lack of vision and a view of bikes as toys rather than transportation. Realistically I don't see it happening until yuppies catch the cycling fever.

Again, until some are built no one has data in retail environments. But why have to depend on Ubars when going to movie or shopping mall? Just last week 2 riders used bikes. One walked it into the building and stored inside an unused room. The other used a post right out front the door. Both were irritated they did not have better options. Not everyone has the desire to put up with these hassles.
