In the absence of forthcoming data (hint hint), what factors do you think differ between the UK and USA which affect the ability of very old/very young drivers?
Car dependency mainly. A 65yo in the UK that dosen’t feel physically capable of driving can still have an independent live, using public transit or walking. In the US you depend on cars for everything.
That doesn’t affect the ability of older drivers, only the number of them.
In fact, since one reason very old drivers might get more accident prone is because they stop driving as much and lose some of the skills, you would expect that, if older Americans really persist in driving more as they get older (you haven’t provided any evidence that they do) they would retain those skills and be less accident prone, not more, so would be safer, and less at need of re-tests, than their UK counterparts.
Focusing on the driving safety of the elderly is a classic example of Saliency Bias. A 20-year old kid wrecking his car is nothing unusual so you don’t remember it when thinking about safety. An 80 year old who can’t even remember which way to turn the wheel getting in a wreck is unusual and extreme, so it’s more salient. Getting stuck behind an elderly driver gives you the impression that they’re a bad and hence unsafe driver, which contributes to this.
That’s from the UK? I don’t think you can extrapolate UK driving data to the US. Roads and car use don’t compare at all.
