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.
It’s self select the drivers that have the ability to drive. A nearly blind old person on the UK can have a fulfilling live walking and using public transit, the same nearly blind old person in the US have no choice but to keep driving.
It’s a shame that you’re so quick to express skepticism but so reluctant to do any research of your own, because the facts are a bit embarrassing with the exact same trend in the USA as in the UK.
Driver safety peaks in the 60s, and only moderately worsens after then. The large increase in fatal accidents, by the way, is clearly a result of older drivers being more vulnerable in a crash - because the chart at the bottom doesn’t show any such large increase for passengers and others.

I’m interested to know if this changes your mind.
