The best safety tip for oldies, is give yourself more distance to stop in emergency.
I have been driving both professionally and for pleasure for over 60 years now, and I know my reactions are nowhere near as good as they were.
Can't say I drive any slower, but I give myself a lot more breaking and maneuvering time.
Got pinched speeding two months ago. Again!
So I'm definitely not getting any wiser with age.
Insurance renewal is going to kill me next month!
