What can your car say about you?
Using a few common sensors, BMW engineers and Chinese government researchers have developed a technology to get a general idea of a motorist’s personality from the way they drive, according to a peer-reviewed paper published in the Journal of Advanced Transportation last month.
“Participants only need to drive for less than 10km (6 miles) before their personality traits can be identified quite precisely,” the joint research team, led by Zhu Tingshao from the Chinese Academy of Sciences’ Institute of Psychology in Beijing, said in the paper.

Zhu and BMW China recruited more than 90 volunteers in Beijing, tracking the motorists as they drove 15km through city traffic in one of the company’s cars.
The researchers compiled data from a small number of sensors that detected factors such as angle of the acceleration pedal, speed and the tilt of the steering wheel.

Each sensor measured the drivers’ movements 10 times each second. Artificial intelligence was then used to link the data to personality.
