Well I spent the better part of 18 months in the1970s driving in Saudi Arabia. They may be the worlds worst drivers. Here are three factoids that applied back then at least, I can't say since.
First, a Saudi living in his tent in the desert gets enough money from the government to buy a home or a car. So he jumps on his trusty camel, rides to the local Mercedes dealership and , having never driven before, drives off the lot in a shiney new car.
Second. I pull up to an intersection with 3 lanes. One is for right hand turns, one is for lefts and the middle one for going straight. Because the light is red I stop in the center lane. A Saudis is stopped on either side of me when the light changes, having been in country and driving a while as the light changes, I do nothing. But the guy on my left makes a right and the guy on my right turned left. Had I gone and been hit by either or both of these cars, under Saudi law, the accident was deemed to be my fault since it would never have happened had I not been in their country.
Third, one of our employees was an Italian mechanic. He needed to get his Saudi driver's license as did all expats. He came to me and explained he was worried he would not pass the eye test as he was blind in one eye. My assistant, a Sudanese gent, who was familiar with how the license test was conducted told him not to worry. They would ask him to put his hand over one eye and read some letters and then tell him to put it over the other eye and do the same. What the mechanic was told to do was to cover his blind eye with his left hand and when they told him to switch, that he should take his left hand down and put his right hand over the same eye. He got his license.
The only place in the world I have ever seen worse driving than in S A back then is in a demolition derby.
