According to a study by DMEautomotive, singing out loud was the top non-driving activity people do in the car — something at least 56 percent of motorists admit to engaging in while behind the wheel. Women are more likely to sing then men: 65 percent to 49 percent, and people under 35 are more likely to rock out (61 percent) than those 35 and over (54 percent).
I sing to anything I like. This article claims less than 50% of men sing in the car. But I sing out loud like I'm the only one on the road. I'll air drum. I'll strum my steering wheel like it's a guitar. Fuck the other drives if they think it's strange. In the car, I get into my music and I don't care who knows it.
