If you want to improve their chances of being alive in 5 years, no. Guys might have more of a tendency to speed, but girls are worse drivers than guys. Ask the insurance companies. They'll tell you. Each of my sons who are driving have totalled cars; a Lexus and a VW. My next son's first car is a used Saturn sitting in the driveway waiting for him.
My wife has been in three accidents, all with teenage drivers, none her fault. One girl turned in front of her. Two guys ran into the back of her, one while texting, one while speeding.
