NBC News - We all do it, or we've caught someone else doing it. Sometimes it's kind of a quiet, go-with-the-flow moment, and other times it's a high-energy performance. It's the most often performed action in a car: singing.

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).

What are we singing? A separate study from Insurance.com finds the favorite song for motorists is that 1981 Journey power ballad, "Don't Stop Believin'." (See below for the rest of the greatest hits.)

A variety of studies have focused on the popularity — and dangers — of texting while driving. The DMEautomotive study echoed those worrisome findings: 26 percent of motorists admit they read a text message while driving; 20 percent said they also are clicking away at the keyboard; and 50 percent acknowledged they talk on the phone.

There are other things that can keep a motorist's attention away from the road. Fifty percent report eating while driving, so, perhaps it's not surprising that the study found 6 percent of men and 4 percent of women occasionally floss behind the wheel. Men are more likely to watch movies or TV: 10 percent compared to 3 percent of women.
