Do you know for a fact that there has been a larger number of crashes (and not just that you are noticing them more or that they are being reported more)?
I agree with Sam2. If women stopped driving there would be 50% less cars on the road and less accidents. Men drove before women did, so we have first dibs.
No but seriously, they should make a mandatory driving test every 5 years after age 65. Been nearly hit by too many older people.
