Sorry for the huge URL, but as you can see it is a two lane road where one lane is blocked by parked cars. To negotiate this you drive past a few parked cars then pull into a space. You can't necessarily see a space to pull in, but if the car that is trying to pass you stops you can assume it has stopped in a place that will let you past. There is often a lot of reversing and swearing. You can see this clearly ... in the distance is a blue car, the driver has noticed that the Google car is coming towards it and has decided not to enter the narrow section until the google car has exited it. Some people will do this, others (as the blue car has priority over the google car) will drive on, making the google car pull into on of those gaps on the left. If there is no gap, google car must reverse and find a gap.
