When I took my driver's test in the USA, my score was based on a rubric and so I could not be penalized for mistakes that weren't on the rubric. I managed to stall the car in the middle of the road but that was fine because whoever wrote the rubric must have assumed that no one would take the test in a car with a manual transmission.
So what I'm saying is that maybe this guy did pass, if there wasn't an explicit "doesn't drive off-road" scoring category...
Same for my sister, she borrowed my RAV4 but stalled it twice during the test. The instructor was impressed she showed up in a manual at all apparently.
I got a verbal warning from the guy doing the driving test about driving on the wrong side of the road when there was an oncoming vehicle (it was a long road) and I assume that was because it wasn't listed as grounds to fail someone. My driving instructor reckoned they all called the tester Nervous Norman and I may have scared him into passing me, so he never had to sit in the same car as me again.
