The other day traffic stalled behind a car stopped at a green light, honking ensured; it was ignored. Finally the driver drove on and promptly stopped at the next green light, more ignored honking. Eventually I caught up to the problem driver, readied the stink-eye, and discovered the driver and passenger smiling and laughing, obviously enjoying a conversation, and using sign language. Ah okay, mystery solved. But is signing while driving safe? One, you need to take your hands off the wheel and two, you have to take your eyes off the road to communicate. So what do you think, is signing and driving okay?
