As has been pointed out here before, in many states it's technically required to give an audible signal before passing on a two-lane road. A driver who taps their horn when they're four or five car-lengths behind you is probably just trying to be courteous.
I totally get that one...I grew up in an area with a huge amount of bikers and to be safe I always did a short honk to notify them that I was there. I wasn't sure if that was the right thing to do or if I was making them upset but I wanted them to know I was there. Thanks for the info!
