writes "The average car on the road is 11.4 years old, according to Polk, a global automotive analysis firm, which reviewed 247 million light vehicles in the U.S. The age of cars has been gradually increasing since 2002, when the average car was 9.8 years old. Polk expects the trend to continue over the next five years. Automotive density is projected to decline to 77.5 cars per 100 people, down from 80 cars per 100 in 2007, according to Kelsey Mays of Cars.com.
Another study, from the University of Michigan Transportation Research Institute, analyzed the reason for the decline in young driver licensing. Of the 618 unlicensed respondents aged 18-39, 26.9 percent said the main reason they did not get a license was “too busy or not enough time to get a driver’s license.”"Link to Original Source
