Men drive 16,550 miles per year, but women only drive 10,142 miles per year.Also, the FHWA suggests that age is also a factor in miles driven. Women who are older than the age of 65 drive fewer miles than any other age group; they average a mere 4,785 miles each year.
Americans drive nearly twice as many miles as they did in 1980, but miles of public roads have barely increased (6 percent). Simply maintaining those roads in their current state costs $101 billion a year. Drivers log an average of 13,476 miles per year, or 37 miles a day. The number of Americans with driverâs licenses increased 45 percent, from 145 million in 1980 to 210 million in 2010. We spend more than twice as much time in traffic congestion â 14 hours per year in 1982 to 34 per year in 2010.
