Honking from frustration at some moron how blocks traffic.... has no effect on getting them to move, but, annoys EVERYONE else around. So, someone in India devised a science experiment to reduce honking. It worked.

In 2013, behavioral scientists Anand Damani and Mayur Tekchandaney invented a device called Bleep that would make an annoying beeping noise inside the car every time a driver honked. To stop the beeping, drivers had to press a red button with a frowny face on it. “A little bit of medicine back to the driver,” Damani said in a TED Talk. They tested the device on drivers in Mumbai for six months and when Damani presented the results — no accidents and a 61 percent reduction in honking — the audience cheered.
