I totally disagree!! There are people of ALL ages that should not be driving. I see them every day.
By the way, I just turned 80, and passed my flight review. I also piloted a P-51 to celebrate my birthday.
First of all, so glad you are still pursuing your passion at age 80. I personally feel much safer with you in the air than I do with you behind the wheel of a car. My comfort begins with the fact that there is a lot less traffic in the air than on the roadway. Most private pilot aviation accidents only kill the pilot and occupants of that aircraft. Many times when elderly people drive and there is an accident there are many more injured/killed because of congestion. My 87 yr old DM keeps telling me not to worry about her when she drives. I tell her point blank, "it's not you I am worried about mom", "it's the people you may kill or mame". Thinking about taking her car away from her in October when she turns 88.
