if I honk at a driverless car, how does the driverless car know what am I honking about ?

If it senses a honk, all sensors will increase alert a do a 360 scan of all possible danger, at the same time slowing down. When I said scan, that does not mean visually only, it means other sensors on the road that are "talking" to the car

It must take into consideration of "false positive" honking too
