As far as we can tell, this study was not commissioned by Lexus or Mercedes-Benz.
Research conducted by the British website Scrap Car Comparison concluded that BMW and Audi owners are more likely to be psychopaths than drivers of other brands.
The study had 2,000 vehicle owners in the United Kingdom complete a 12-question test that rates their psychopathic tendencies on a 36-point scale.
The average score was 6.6, but BMW owners nearly doubled that with an average of 12.1, followed by Audi at 11.7. No other brand scored higher than 7.0. Toyota and Kia scored lowest among brands sold in the U.S.
The study also found that electric vehicle owners scored higher than drivers of gasoline vehicles and hybrids.
"The findings suggest that these drivers may be more likely to exhibit psychopathic traits such as superficial charm, grandiose sense of self-worth and a lack of remorse or guilt," Scrap Car Comparison said in a blog post.
