One size determinations fits all are not an honest evaluation of elderly people. She seems fine to me.
This is not about an accident caused by a woman too old to drive. It’s about theft and a victim of theft. She’s working so if she is feeble as you accuse, she would not be doing that.
On the other hand, there’s cause for concern when elderly people do drive because they have higher rates of fatal crashes per mile driven, per 100,000 people, and per licensed driver than any other group except young drivers. A problem is that elderly drivers don’t deal as well as younger ones with complex traffic situations, and multiple-vehicle crashes at intersections increase markedly with age. Elderly drivers are more likely to get traffic citations for failing to yield, turning improperly, and running stop signs and red lights.
