Brief conversation today at a stoplight...
Guy in SUV: "Excuse me - what are those discs for on your wheels?"
Me: "What's your best guess?"
SUV: "Well, they say 'eco-something' on them, so I'm guessing wind resistance?"
Me: "Exactly."
SUV: "So they save gas?"
Me: "A tiny amount"
SUV: "Is it worth it?"
Me: "It all adds up!"
SUV: "Last question: are they expensive?"
Me: "Nope - I made 'em!"
The light changes and we part ways, and I'm wondering if he'll be trying to find "eco-something.com" on the interwebs later. I also wonder if he asked about price because he liked them?
