We slept here in our suv for over week while visiting San Francisco during the days. Atleast 5 or 6 other rv's and car-campers were here every night too. Didn't have any problems. Working water fountains, always open washrooms. Bridge Patrol and Highway Patrol drive through every 20 minutes or so and never say anything. There was even a guy sleeping in a tent setup in a parking spot one night and they just drove right by. Fantastic view of the bridge. Sign even says that small stove use is allowed if done safely.
