There are more older drivers on the road now than young ones, says a new University of Michigan study, prompting researchers to ponder: Who's safer behind the wheel? New drivers or old drivers?
U.S. drivers had better hope its the latter, because a sinking percentage of younger drivers are getting their licenses. Aged drivers represent a growing share of motorists.
In 1983, a third of all drivers in the U.S. were under 30 and 50% of all drivers were under 40 years old. In 2008, just 22% of drivers were younger than 30 and 40% of all drivers were younger than 40.
