Car Forum / UK Car Forums / Driving (UK group) / November 2009Woman passes 950th driving test !
Ha! and that was only the written test. She still needs to pass her practical to get a licence!! http://news.bbc.co.uk/1/hi/world/asia-pacific/8347164.stm Bod Bod explained : > Ha! and that was only the written test. > She still needs to pass her practical to get a licence!! > > http://news.bbc.co.uk/1/hi/world/asia-pacific/8347164.stm > > Bod I would have thought that anyone could pass the test, even giving completely random answers, with 950 goes at it.

Yes, you'd think by the laws of averages she would pass. Bod Bod expressed precisely : > Yes, you'd think by the laws of averages she would pass. So should there not be a limit on how many goes at it you get?

Not sure about that, my brain says yes but my heart says no. Bod > Bod explained : >> Ha! and that was only the written test.

You have 50 minutes!

My head is aabit disfunctional at the mo, I think I'm coming down with flu. What is the answer? Way below 950 is my guess.

You've already said that "anyone can pass ... given 950 goes at it". I'm disappointed if you were only guessing. I think you don't really have a clue. Agreed? Phil the Farmer formulated the question : > You've already said that "anyone can pass ... given 950 goes at it". Only part of my sentence quoted, which changes the context completely. > I'm > disappointed if you were only guessing. I think you don't really have a clue. > Agreed? Not quite. The answer is that she would have required many more go at it to suceed by chance alone, but given that she ought to have some clues and some common sense, that alone ought to have improved her odds tremendously. So it is anyones guess how much is luck and how much is skill. The question remains - Should a shotgun technique be a fair and safe method of testing someones ability to drive on public roads? When it comes to her practical part of the test, how many goes should she be allowed at that? Does anyone here think she would be then fit to drive on public roads? I certainly do not.

Really, you would need to see a graph showing the number of attempts to pass, but my own suggestion would be that 20 allowed attempts ought to be more than enough. Beyond 20 the question ought to be asked are they really suited to driving at all. When it gets into the hundreds luck in guessing becomes much more of a factor and actual knowledge less.

Mind you, if it took 950 goes at the written test, I can't see her passing her practical test in our lifetime.

Why not ? Sir Jackie Steward might have had a problem with a written test. >> Bod explained : >>> Ha! and that was only the written test. [quoted text clipped - 13 lines] > > You have 50 minutes! On an individual test, the chance of getting 60% (or higher) by picking answers randomly are 0.000000601. Repeating the test 950 times randomly gives a probability of one or more successful passes as 0.00057, or 0.06%. To stand a 50% chance of passing by guessing randomly, she would have to take the test 1153500 times. > Ha! and that was only the written test. > She still needs to pass her practical to get a [quoted text clipped - 3 lines] > > Bod I would say anyone taking this many tests and failing was simply too thick to be allowed to drive. You need a certain level of intelligence to drive, especially nowadays when our roads are so busy. Imagine what her reactions must be like on the road if she's so thick it took her all these attempts to pass just the written test. Thank goodness I'm old and never had to do a written test!! >> Ha! and that was only the written test. >> She still needs to pass her practical to get a [quoted text clipped - 11 lines] > it took her all these attempts to pass just the written test. > Thank goodness I'm old and never had to do a written test!! In retrospect, it is an unbelievable amount of goes at it. Even a hundred attempts is, really 90 goes too many. Bod |
