I’ve noticed that drivers feel a sense of entitlement to the road. They feel superior to pedestrians and bikers. I’ve often seen drivers yelling, speeding and honking their horns as a way to express their frustrations, causing not only noise pollution but also endangering people lives.
I’ve always found road rage to be an incredibly counter productive expression of emotions. People tend to yell at the top of their lungs when they are completely aware of the fact that the person they are yelling at will not be able to hear them. Honking horns has its place on the road but most people end up honking to relieve stress instead of what it is intended for. People tend to speed and overtake other cars to express their aggression.
Growing up in New York I’ve have not had to drive much but do remember trying to stay calm in situation that frustrated me. However I never expressed my emotions by yelling, honking or speeding.
Sensors built into the steering wheel could detect when you have an elevated level of negative emotions and reverse the horn from honking outside to inside or maybe you only have a certain amount of external honks per ride after which it would reverse.
Similarly the car can monitor your emotions and limit your speed based on how angry you are.
And lastly a recorder could detect when you raise your voice over a certain level and record your yelling. This would then be played back next time you start your car to show you what you would say in a moment of rage aiming to possibly help you recognize this behavior and sympathize with people who hear you behave in this manner.
