One of many examples would be a single lane street which goes up a hill and around the corner. Although there is only space for one car you can drive both directions. Rather often than not you have two cars meeting in the middle and then one car has to drive back to let the other car pass. This is pretty difficult to do as a human and I am not sure how an autonomous car would do that.
