I was reading about this lady in South Korea who has failed a written drivers test 771 times. She only needs a 60 percent to pass.
Statistically, it seems impossible to fail that many times. Maybe she should move to San Francisco.
When I was taking the written driving test in SF (and passed) there was an Asian lady there who failed. She maybe had 25 percent correct. So the DMV marked in red the wrong answers, circled the correct responses, and then gave her the same test again to do right. Unbelievable.
