I'm afraid it's worse than you think Eric. A few years ago a friends kids were in one of the few school driver training classes still around. The instructor told them "Your parents will tell you it's wrong, but when two cars come to a stop sign at the same time, the vehicle to the left has right of way". Maybe in the U.K. but not in countries with driving on the right. I was a volunteer police officer at the time and went so far as to consult my traffic manual. Just what I thought, he was wrong. This instructor kept it up until a local reporter got a ticket and had to go to traffic school. Since a writer has to write about something, she wrote about her driving class. Imagine the judges joy when he read her article. Basically, what she said was "I always thought the vehicle to the right at a stop sign had right of way. Now that I've taken this class, I know that's not right."
