Here's the data on 80 year old's driving:
In 2019*, 203 drivers aged 60 and above were killed, 1,868 were seriously injured and 7,640 were slightly injured in road accidents in Britain 5 . Although the casualty trend for this age group is decreasing, it is decreasing more slowly than for other ages. The risk of being involved in a road accident increases after the age of 70 years, but up to that age, drivers are no more likely to cause a crash than to be the victim of another road user’s mistake. However, drivers over 70 years, and especially over 80 years, are more likely to be at fault when they crash.
Underlying health conditions, and some types of medication taken to treat those problems, are a common factor in accidents involving older drivers. Indeed, a proportion of older driver fatalities occur when a driver dies of natural causes while driving, and their vehicle immediately crashes.
Older drivers are commonly involved in collisions at junctions, often because they misjudge the speed/distance of other vehicles or fail to see a hazard. Visual impairment may be a factor in this type of crash. Due to their more fragile health and physical condition, older drivers are more likely to suffer injuries when they crash and/or to take longer to recover from their injuries.
60 is old - and I say that as a 50 year old. A 27 year old might not feel young but it doesn't mean they aren't. You can be old and still be fit, active and doing lots of interesting stuff, you don't have to be young to be engaged with the world. I don't want to have to try to look young or pretend I'm still young at 60! I also wouldn't want to be a mother of a teenager at 60, there's nothing wrong with that.
Personally I hate that being old is seen as some terrible horror and that we must all believe/pretend we're young forever.
