In my 120+ highway miles a day, I see more women talking on cell phones while driving than not. However, kids (male and female aged 18ish-25ish) are often the worst drivers, living in the left lane while not passing and swerving like they were drunk, while people with political campaign bumper stickers (both right and left), oddly enough, tend to stay in the right lane under the speed limits.
Folks with union bumper stickers (usually huge pickups) are the ones going 20+ over the speed limit and will ride up on your a**, even if you have traffic in front of you. It’s so tempting to hit the brakes at times.
In life overall, women are disempowered, in that they can't do all the things men can do. This frustrates and angers them. To express their anger and hostility in a public setting would most likely get their butt kicked. Thus, when they get behind the wheel and are protected by steel, they are able to express their anger and hostility overtly with absolutely no consequences (unless there is an accident or they get pulled out of the car at a stoplight). I see it every day, and can oftentimes predict their crazy maneuvers ahead of time.
I don't say this to demean women, but rather throw it out there because it has helped me avoid accidents in the past.
