Interesting that he interprets the pedestrians' wave and skip as a sign of gratitude. I think he's right, it is, but it's also a sort of bow and scrape. And why should people be grateful to a driver for allowing them to continue walking over a zebra crossing? Well, from an Ogmios spiritual perspective I suppose we should all be grateful for everything, and I'm sure Ogmios is also grateful for the opportunity to allow them to cross.
