I would've thought the lack of car parking everywhere I go would've taken care of this by now...
When I used to live in Northern California, I'd see people idling in their cars in the parking lot waiting for a space or stacked up at the entrance to the parking lot. I could swing by on my bike, lock to a pole or tree, go in, get what I need, be back on bike and on the road while many of them were still idling. I wonder if any of them ever noticed and said to themselves, "Wouldn't that be nice? I wonder if I could...?"
