Google has proposed the mechanism that can mimic human behavior to communicate with the pedestrians.

The robotic hand gesture and the suggested robotic eyes on the exterior of the car would help the cyclists know about the presence of the vehicle. The robotic hand could mimic the human gestures' signaling 'sweep' to pedestrians to cross the road.

As per the patent document, the company has used the mechanism of flashing alerts like 'stop' and 'safe cross' to maintain the on road safety of both the car and pedestrians.

The uncrewed vehicle is set to have a range of sensors and roof-mounted lasers to map the environment.

Google's uncrewed vehicle is up for safety test and the company is further working to make it safer on the road. Google plans to make the car available for masses by 2020.
