Google, a leading company trying its best to have an autonomy in self-driving car, has admitted in its patent document filed in the year 2012 that its innovative self-driving car does lack ability to communicate with other pedestrians regarding what the car is about to do.

In the patent filing, just approved, the giant states that the innovative cars may have instruments like sensing devices to sense if walkers are trying to cross the road, make a sudden decision that what the appropriate response should be at that time. And they are to be informed about the move cars are going to take; it would show a notification to make them know about the next move.

As the patent paper states, “the vehicle may comprise of a physical signaling instrument, an electronic sign or lights, a speaker for giving distinct notifications.”

While driving a car, the people hardly communicate with the outside world and it is probably one of the weakest aspects of today’s autonomous vehicles. We individuals have a complete range of media to convey the message from a short-term flash of the headlights or hazards up to somewhat more obvious physical gestures.

In the age of “Internet of Things,” we all intend to be with the communicative devices whether it is handheld or advanced vehicles. Google’s innovation to make a self-driving car is actually a ground-breaking in itself, yet it should have a comprehensive communication mechanism.
