The more you drive the more you notice things. After a few years in the taxi, while going through the tunnel in central Phoenix, I pointed at the cars in the far-left lanes of the freeway and said to my passenger, "you see that car right there? It's going to change into the next lane, and that other guy is going to have to slam on his brakes." My passenger was amazed when exactly this happened seconds later.
