I may have convinced a colleague of mine to join the community of bicycle commuting (at my work of 1,000+ employees, the bicycling community is presently a population of one - me).
She was telling me how she goes to the gym every morning to do spinning and oh how she likes to keep fit.
I asked her if she ever noticed all the steam condensation dripping from the big glass windows of the gym. "Yes!" she exclaimed, "It's really humid in there."
I asked her where she thought all that humidity came from. Hmm... somehow the answer eluded her. "That water dripping from the windows is condensed Human Vapor", I explained, "It is natures way of letting you share the exhaust of the sweaty guy across the room."
Of course, that thought was not appealing to her. I suggested that instead, how about she rides her bike to the gym and then turn around and ride home without ever going inside the sweaty gym. She would get the same amount of spinning time and could do it outside.
"Hey, that's a good idea!", she realized. But, hmmm, why doesn't everybody do that?...
"Well, hey, why don't you just ride your bike to work, save yourself the hassle of going to/from the gym, get the exercize along with fresh air, and save your auto for better purposes. Plus, you will be an enviro-hero!"
My colleague still seems bewildered as to why this makes so much sense, but is so overlooked.
Let's hope I see her bike chained up to the "handicapped parking only" sign-post one day soon (we don't have bike stands here...yet.
