Ever been stuck in traffic and the person behind you started hooting incessantly? Car hooters are designed to warn, not irritate, and this is something that Google has picked up on. During the company's latest report on its Self-Driving Cars Project, the engineering team noted that it’s teaching their cars to be more "polite" when using the hooter. 

According to Google, their cars now know the difference between hooting at a car that is going the wrong direction in a one way, and one that is performing a three point turn in front of it. As such, the cars have learned the proper response, and some hooter etiquette, in dealing with these kinds of situations. How other drivers will respond to these polite hoots remains to be seen, but Google says that in time, their cars will also be able to predict how other drivers will react to how the Self-Driving Car hoots. 

Our advice is for Google to bring a few of its Self-Driving Cars to the Joburg CBD, and see just how far polite hooting gets you.
