The shift from male to female is fascinating. In younger drivers accidents are disproportionately male, I guess due to high testosterone buffoonery but in older drivers it's disproportionately female. My personal observation is that older male drivers are much more slow and less confident whereas females tend to be overly confident and driving way too fast, especially the ones in huge cars.

According to this women become more dangerous than male 17-24 year old drivers only when they reach 80+ whereas for men they only become more dangerous than female 17-24 year old drivers at 86+.

I actually think more should be done about younger drivers than older.
