As this episode opens, Walter and Shirley are driving on El Cerrito Place and turn right on to Outpost Drive. The street signs are visible. The next street level scene shows them driving though the same intersection from the opposite direction just before they hit someone in the street. It is unlikely they drove on Outpost Dr for a short distance and made a U turn.
The accident involving the pedestrian occurred near the intersection of El Cerrito Place and Outpost Drive yet the police state that the incident occurred on "Windsor".
