Google's Self-Driving Cars Will Honk At You If You're Not Paying Attention

Prototype vehicles are now able to recognize when honks are appropriate and even modulate how they use the horn, the company said in its most recent monthly report. "As our honking algorithms improved, we've begun broadcasting our car horn to the world," the report said. "If another vehicle is slowly reversing towards us, we might sound two short, quieter pips as a friendly heads up to let the driver know we're behind," it continued. "However, if there's a situation that requires more urgency, we'll use one loud sustained honk." Driverless cars may be the future, but we're not getting there all at once.
