These road tests are pedantic. You gotta check the mirrors, keep both hands on the steering wheel and what have you. Most of us do not follow all these rules when driving everyday because we've driven enough number of times that we do things instinctively than follow training. For example, I always drive one handed - not allowed during driving tests. If driving test standards were applied to our everyday driving, most us would have our license taken away.
And language and communication ARE an issue. What if one doesn't understand what "make a 3 point turn" means? Not that they dont know how to. What if they just dont understand what the examiner is asking for? Or what if the guy failed so many times that he was super nervous going in and made mistakes? Pressure can make you, make mistakes.
Then again, I agree there is a possibility he was just a terrible driver. But failing 11 times tells me it is less about his driving skills than certain other factors such as language, communication, nervousness, forgetting to do certain things etc., Insisting this is solely about his driving skills is silly. You dont know that.
I agree that road tests are pedantic, but the driving school has to prepare students for that. One-handed driving might be frowned upon during a road test, but it is not illegal by itself. I can't see someone failing a road-test just because they drove one-handed and had no other issues, but obviously it is up to the examiner's discretion.
You could have a point that the road tests are too pedantic and don't reflect real world driving. If that's really the case, what changes would you make to make it better reflect real world driving? How would those changes deal with the vast difference in urban vs rural driving? You could pass a test in Moosonee and be ill prepared to deal with driving in the GTA. It's fair to talk about changing the standards, but there still needs to be one. If there isn't a standard or if it's very opened ended, then licensing has little meaning like the Pleasure Craft Operator Card where you don't have to take an in-water test with your boat.
There's no way to prove or disprove that most drivers would lose their license for not meeting driving test standards based on casual observations alone. If it were true, that would mean that most drivers are breaking many laws and the police would be having a field day. Having said that, I definitely would fail at parallel parking (besides not being in the G road test) because I seldom if ever do it and my car doesn't have parking assist. I always go to a parking lot as it's much more convenient and wont' hold up traffic. I suspect that suburban drivers would also have difficulty with parallel parking without assistance.
Insisting that he failed mutliple times because of language, nervousness, forgetfullness, etc is also silly because we don't know if these played a role nor is there any evidence. He didn't show his past or current driving test results, so we have no idea what he did wrong and what he did differently to pass this time. In addition, the G road test does not test for the 3-point turn at the moment. If he doesn't understand instructions then he's responsible for asking the examiner to repeat or clarify them regardless if there was an accent.
Someone that fails a test multiple times and makes the same mistakes has not taken corrective actions. Whether or not these mistakes were caused emotions, language barriers, forgetfulness, lack of skill, fatigue, wrecklessness, etc are besides the point and should be taken care of.
