Japan Moves To Ease Aging Drivers Out of Their Cars (nytimes.com)

As Japan's population ages, so do its drivers. Japan has the oldest population in the world, with nearly 28 percent of its residents above 65 years old. One in seven people are over 75. In the United States, by comparison, that figure is closer to one in 16. From a report: According to data compiled by Japan's national police agency, drivers between 16 and 24 are more likely to cause traffic accidents than any other age group. But last year, drivers over 75 caused twice as many fatal accidents per 100,000 drivers as those under that age. Among drivers over 80 years old, the rate was three times as high as for drivers under that age. The news media regularly features grisly reports of deaths caused by older drivers, some of whom are later discovered to have Alzheimer's disease.

Since 2009, all drivers 75 and older must submit to a test of their cognitive functioning when they renew their licenses [Editor's note: the link may be paywalled], typically once every three years. Under a new traffic law that took effect in March 2017, those who score poorly are sent to a doctor for examination, and if they are found to have dementia, the police can revoke their licenses. More than 33,000 drivers who took the cognitive test last year showed what the police deemed to be signs of cognitive impairment and were ordered to see a doctor. The police revoked just over 1,350 licenses after doctors diagnosed dementia.

    Yes, that does make some sense. But are we talking about 200000 drivers, 2000, or 2? And "twice as many" is how many, exactly? Also, what percentage of people in that age bracket still drive?

    Telling us the rate "per 100000 drivers" without context doesn't actually explain how large or small the problem is. It just tells us that any particular older driver is more likely to cause a crash than any particular younger driver.

      "More than 33,000 drivers who took the cognitive test last year"
      That means more than 33,000 drivers 75 years or older, because that's how many failed the screening test and were referred to a doctor.

      That's also only those who had to take the test, which is only required once every 3 years.

      From TFA:
      "An additional 460,000 older drivers showed slight impairment of their cognitive functions, based on their performance on the test, but were allowed to keep their licenses if they took a three-hour traffic safety course."

      That's half a million drivers who either failed or showed slight impairment in 1 year on a test only required every 3 years for >= 75 years old.

      That's 1.5 million dodgy or failed results. There must be many times that who passed the test, so we're not talking 200000 drivers, we're talking millions.

    Age discrimination of young and old over "safety" related arguments is repulsive. People were once free to travel anywhere they liked without the permission of governments. The idea that safety is so much more important than the population's right to travel is disgusting. And don't go tell me how its a privileged and not a right. It's been understood that people have an inalienable right to travel and the courts reckless disregard for that right has resulted in all sorts of discriminations and tragedies that mostly have no significant impact on safety- but it's an irrelevant argument to me because no amount of improved "safety" can justify the restriction on peoples rights to live outside of a repressive regime.

    While the famous Ben Franklin's quote below may be understood out of context to mean something that was not intended it is that interpretation that sums up nicely what I believe:

    "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."

    The young are discriminated against and hindered from gaining the skills needed to drive safely and this results in less experienced older drivers. By increasing the age you end up in a never-ending-cycle and argument for increasing the driving age. You can continue this up to and past age 28 because of "brain development". It's ridiculous when you can't hire a kid out of college because the state demands a year of experience with a parent or other adult before they can drive. This has literally prevented me from hiring numerous young persons out of college! At least until I moved my business out of an insane state with this requirement.

    Then there are laws in other states where they suspend peoples drivers licenses for "crimes" or debts that have nothing to do with safety and safety isn't even why we have drivers licenses. It was bigotry back in the early 1900s against motor vehicle owners and up until the late 1960s there were even states that had no testing of drivers either oral or road to get a drivers license.

    One example of a "crime" that is punished via the restriction of ones driving "privileged" is a NY law that applies to juveniles only (or did) that says if you are caught committing a graffiti crime that you will be prevented from getting a drivers license for a number of years after you otherwise would be able to get one. This doesn't apply to an adult who commits the very same crime! In theory we're suppose to be more lenient with minors and yet frequently the opposite is true. It's a more serious crime or only a crime in many states for a young person to smoke weed- but it's either legal or merely a violation for an adult to do the same thing!

    Another group that is discriminated against via drivers licenses suspensions that has nothing to do with safety are people indebted to the state for child support. You might think "Good." because those people are costing us money. The problem with this thinking is a lot of these people didn't even know they had a child because mothers have denied that these kids are the father of the father. When it finally comes out that a father is in fact the father and should have been paying child support the debts to the state (to reimburse the state for welfare basically) have there drivers licenses suspended. Not everybody has 20 or 30 thousand dollars to cover the costs the moment it is decided in court that they are the father and in debt to the state. It's entirely unreasonable for a person to be made to pay on the day of the court ruling that kind of money to the state else face a suspended drivers license. And it doesn't even make sense because you are not hindering that father from employment that would enable him to repay that debt. It's another form of debtors prison that even the British understood hundreds of years ago was a bad idea- and so it was abolished- but not here in the good ol USA.

    I'm in Canada. Doctors are required by law to report any medical condition that may affect one's ability to operate a motor vehicle, and such a report triggers an immediate suspension of your driving license. (Driving while Suspended carries the same penalties as Impaired Driving).

    In my case, at age 57, due to a mix of medication my doctor prescribed me, I began experiencing dizzy spells. Combined with low blood pressure (which is actually good, as you age, but when I was a young adult I would get a dizzy spell for about 1~3 seconds if I stood up quickly from a seating position) I fell and hit my head while in the doctor's office, and he sent the report (and paid for a taxi home for me).

    Now my Driver's License is pretty much exactly like how all Pilot's Licenses work ... it's dependent on a medical. I take the medical every year (the licensing agency pays the fee to the doctor) and if I pass (I always do) then I can renew my Driver's for a year. This will never go away; I will be doing this for the rest of my life.

    Note that the medical also includes a vision test, which I also always pass (20:20 & 15:20), but should I fail then there would be a requirement to get another medical from an optometrist, and I know many drivers who cannot see as well as I can and don't wear corrective lenses.

It's always tempting to put the bar as high as possible because it's good for the traffic deaths, but you have to balance it.

    A way to shift the balance then is to take in account driving aids: autopilot/lane assist/collision detection etc allow the driver to act more competently, so you could have a category of drivers who are not allowed to drive in a basic car.

(doens't have to be as hard as a pilots license but it should be a lot harder than it is and include cognitive function testing and a physical exam) Do something stupid like drive drunk and your license gets revoked on the first offense because you have clearly demonstrated you cannot handle the responsibility. If you are getting older and lose the ability to cognitively react fast enough and properly while driving, that should result in your license being suspended. I don't see why that should even be controversial. Simple fact is that you become dangerous when that happens. I expect/hope I live long enough it happens to me someday.

People in this category should not be driving under any circumstances because they are a hazard to themselves and those around them. Right now we have frankly set the bar too low.
