Many Westerners live in their cars. That is, they do things like eat, apply makeup, make love, and maybe even shave as they drive. Most Chinese still live on their bikes. I have reported of some of the activities I have seen the locals do on their bikes like hold hands.
Just now, I saw a man eating sunflower seeds on his bike. One hand was steering; the other hand had a handful of seeds. The cyclist chewing and spitting on his way home.
