As many have reported, I really dislike the horn button location and consider it a design flaw, or better said, oversight. However, I hardly use the horn and try to avoid it since it can lead to further aggressive behavior (I live in NY). Remember the friendly tap on the horn that you would use to say "hi" when passing a neighbor's house? It simply can't be done on the Model S refresh. Would love to see an OTA update that would restore the horn to the center wheel hub, then create a new shortcut or function for the original horn button. This would be a great holiday update.
