I know when I was taught to drive, I was taught in a residential neighborhood where people had cars parked right up to the corner, so at the stop signs I could not see oncoming traffic. Since I could see the road in front through gaps in the parked cars, being allowed to do a California roll would actually have been safer, as I could have gone through the road when I new there were no cars in it, instead of having to stick the nose of the car out when a car might be zooming past for all I knew.
