Are girls now worse drivers than boys?

This was only one study, but it fits into some broader social trends:

In a survey of teenage drivers, Allstate Insurance Co. found that 48% of girls said they are likely to drive 10 miles per hour over the speed limit. By comparison, 36% of the boys admitted to speeding. Of the girls, 16% characterized their own driving as aggressive, up from 9% in 2005. And just over half of the girls said they are likely to drive while talking on a phone or texting, compared to 38% of the boys.

Nor are these teens meta-rational:

The study found that 65% of the respondents, male and female, said they are confident in their own driving skills, but 77% said they had felt unsafe when another teen was driving. Only 23% of teens agree that most teens are good drivers.
