And that’s basically it!
It's multiple choice, the passing grade is 43/50, and you can take practice tests online.
I genuinely think this person has a mental disability, I can't think of any other explanation.
the passing grade is 43/50,
They might just be randomly guessing and hoping that they'll eventually get it, and thinking that their chances are better than they are.
I think that that'd be...let's see. Say there are four possible answers for each question. So he's got a 75% chance of failing any individual question.
$ maxima -q
(%i1) load("distrib")$
(%i2) cdf_binomial(7, 50, .75);
(%o2) 1.8188415357867314E-19
That should give the probability of failing at most 7 answers out of 50 if there's a 75% chance of failing any one.
So he's got something like a 0.000000000000000018188% chance of passing the test by randomly guessing.
His chance of failing a single instance of that test:
(%i3) 1-cdf_binomial(7, 50, .75);
(%o3) 1.0
Ah. He has such a ludicrously small chance of passing that Maxima can't represent it with the current floating point precision.
kagis a bit to figure out how to do this
Okay, apparently Maxima has bigfloats, but they default to only 16 digits of precision; not enough for this. This should give us 200 digits of floating point precision with bigfloats.
(%i4) fpprec:200;
(%o4) 200
(%i5) 1-bfloat(cdf_binomial(7, 50, .75));
(%o5) 9.999999999999999998181158464213268688894671703526026636336767389444876177016785501194817697978578507900238037109375b-1
Okay, so now chance of failing 128 tests in a row by randomly guessing:
(%i6) (1-bfloat(cdf_binomial(7, 50, .75)))^128;
(%o6) 9.9999999999999997671882834192983948674103659072385593201782461674117226992783470289641501110105148249790638571335177402867593272110042747272666144926576839664587182158166580514670324207313719393913737b-1
So then his chance of managing to get at least one success out of 128 tests in a row by randomly guessing:
(%i7) 1-(1-bfloat(cdf_binomial(7, 50, .75)))^128;
(%o7) 2.328117165807016051325896340927614406798217538325882773007216529710358498889894851750209361428664822597132406727889957252727333855073423160335412817841833419485329675792686280606086263120236298536839b-17
So he's got about a 0.0000000000000023% chance of passing at least once in a 128 random-guess-based series of test attempts (assuming, again, that each question has four multiple choice answers). That is, he could keep doing this for the rest of his life and he's virtually certain not to pass.
thank you for doing the math. my brain is satisfied
You didn't need to do all that math out to explain that mental health issues cause people to act irrationally.
Oddballs who dive into absurdly lengthy calculations of something trivial do it out of a bizarre, joyful compulsion, rather than necessity.

My dad is a retired driving instructor and has come across people similar to this. Undiagnosed learning difficulties are probably part of it, but in many cases the people that struggled also had English being not a native language. Maybe it is the combination of the two in these extreme cases
There are also people who are just crippled by test taking anxiety. That’s probably not a good indicator for their driving ability either, though
With questions along the lines of: "You approach a zebra crossing with 2 pedestrians on it, do you:"
A) Honk your horn
B) Wait for them to cross
C) Run them over
D) Get out and rugby tackle them to the ground
E) Wait for the zebras to cross
D, but only if they're tory voters
this is not an all options might be valid?
There are countries where you would need to undergo a psych evaluation if you fail more than x times
In the state I learned to drive in, if you fail a driving test 3 times (to be fair that is the actual driving exam, not the learner’s permit paper exam) then you have to get clearance from the governor to be allowed to take it a 4th time.
Failing 3 times definitely indicates you will have some serious issues driving safely. Its not that hard to get a minimum score of 70/100.
The paper exam idk if the rules are the same. But still, failing 128 times is seriously indicative of ones ability to learn the rules of the road
That’s probably a good idea.
I'm glad this person won't be endangering innocent drivers
Is he a sea sponge, by chance?
FLOOR IT!
Can we all agree that maybe after you fail as many times as there are questions, you just aren't allowed to drive?
Boris Johnson’s at it again
These people are gonna be crashing
Spongebob?
Have a foster kid...uh 19 year old (extended foster care up to 23) that is on her 5th or 6th attempt? I bought her a car but I'm not even sure if she's interested in driving.
What an absolute numpty!
Silently crying in German, knowing this to be the price here if you manage to pass on the first try...
Don't spread any misinformation. The price for the theoretical part is 25€.
If you take the test 128 times, that comes out to 3200€, a number very similar to the one mentioned in the article.
The article does not talk about the total cost of obtaining a driver's license.
Have to backpaddle, as you are right.
I now have read the article and the fees given in the heading actually refer only to the theoretical tests.
Got a different impression before based on the brief, as it also mentioned the practical test...
But unfortunately, that are not the only fees you have to pay.
Minimum pay is ~2500€ if you are lucky, to cover all the mandatory parts you need to get a license.
Theory is £23, practical is £62. The test depends on how long it takes you to learn and get comfortable driving. £80 for a 2 hour session, repeat say 15 times gives you £1285. It certainly isn’t cheap and just climbs the longer it takes for you to be be “test ready”.
ls there a mandatory number of driving lessons or would it be possible to just do the tests and get the license for £85?
E.g. for the rural kid that started driving agricultural equipment on private ground at age 5?
No you can just give it a go at any time one you pass the theory test. You just need a vehicle and a means of getting to the test centre, so someone who’s had a licence for 4+years sat in the car too and L plates affixed.
But they are pretty stringent with how you drive. So no unnecessary hesitation, driving economically, and otherwise doing things “by the book”. You get get marked down with minor faults (such as stalling the vehicle or touching the kerb) which are fine, but get 15 and it’s an instant fail. Likewise with a single major (like running a red light or failing to stop at a Stop sign) it’s a fail.
Not the point of the article though.
