There was a newspaper I read years ago which informed us that "the two cars were travelling behind each other in the direction of Dover"

plus I remember being surprised at reading in a local paper that athletes were about to run the world's first underground mile in a disused mine shaft in South Africa. So far so good. Except that the mine shaft was described as being 18 feet wide and 3 feet high.... I don't know if it qualifies as a grammar error as such, but it was hard to see how the athletes were going to get up any speed with their knuckles knocking sparks out of the floor.
