When I bicycle to work, I use a prominent surface-street overpass.  Today I saw my state senator there.  He was waving to the rush-hour motorists on the freeway below.  As I approached on his side, he turned around and gave me an energetic thumbs up.  I guess he liked my bike, or thought I was making good time.  I was making good time, so I gave him a thumbs up in return.  I like my bike too.
