Sometimes other drivers can make you crazy. Maybe you’ve gestured to boneheaded motorists, safe in the anonymity of your car and the flow of traffic. Perhaps you’ve let your anger at other drivers get the best of you at times because there’s no one else in the car to judge.
But State Farm is on the case. It has developed plans to monitor your every move while you’re driving, measure your emotions, detect angry behavior and deliver stimuli such as music to calm you down.
The plans, as revealed in a patent application, would combine biometric measurements with automotive data to create a “total impairment score” that could be used to set customized car insurance rates.
“Every year, many vehicle accidents are caused by impaired vehicle operation,” State Farm says in its application, recently filed with the U.S. Patent and Trademark Office. “One common kind of impaired vehicle operation is agitated, anxious or aggressive driving.”
Are you sweating, yelling or waving your arms while you drive? State Farm’s “emotion management system” would use a variety of sensors and cameras to monitor your biometrics, including:
State Farm envisions an “emotion management system” that goes beyond just monitoring behavior. The system would store profiles for each driver so, for example, it would learn which music might reduce your hard braking or persuade you to stop tailing the car in front of you. This might spell an end to your loud music.
Each time you end a trip, the State Farm system would analyze the data and update your impairment score, which you could check on your mobile device.
Because the purpose of the patent application is only to describe the system, it leaves many unanswered questions, including:
- Heart rate
- Grip pressure on the steering wheel
- Body temperature
- Arm movement
- Head direction and movement
- Vocal amplitude and pattern
- Respiration rate

- How much would it cost per vehicle?
- Who would pay?
- How often would you have to refill your fragrance containers?
- Adjusting your insurance rate, up or down.
- Requiring you to buy a minimum amount of auto insurance, or limiting how much it will sell you.
- Offering you a discount for using the system.
- Flagging your policy for possible cancellation.
