CARMMUNICATION / notice button

People communicate in various ways.
Many situations occur on the road but communication is scarce among cars, because there is a limited means of communication for people inside the car.
At various situations that can happen on the road this device helps smooth communication.
When you are driving a very sick person to the hospital and wants to go fast / when you are in the middle of the road because of an accident / when your car broke / when you think you need to keep distance with the following car because of bad weather, etc.
