Did the study not look at Florida? They get no snow, the roads are perfectly flat, and on days when it hasn't rained for days, you can still find cars that have spun out for no reason.

Is it the state with the highest % of women drivers?

Tennessee drivers are even worse. You got the no turn signal thing going on, arguably even more rampant, and the roads would constantly get clogged up because Bubba decided to go five miles below the speed limit on the passing lane to pass Brenda who was going ten below and never bothered to get back on the right lane.

Obviously they did not 'study' Texas. On any day you can travel any loop and see 4 or 5 cars driving 100 MPH in crowded traffic. That is stupid in any state.
