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.
When you correct for population size, I think you’ll see that difference largely, if not completely, goes away. There are more women than men in the UK from age 50 upwards (https://www.populationpyramid.net/united-kingdom/2025/)
