Robbing the public of walkways and green space

The land-grabs of foreshore Sydney is on everywhere. The small strip of green along East Esplande, Manly Cove is being conquered with the help of 4 WDRs and a lot of semi-commercial boating gear. Both the green strip and the pedestrian strip are being regularly squatted and people are excluded from using it. No one there to enforce the right of people walking (in the very few spaces set aside for them) and enjoying the Cove.
What would happen if one of these SUVs ran over a person on the 10 km/h walkway-only?
Why is the public excluded from using the green strip and their walk-way?
Watch them make an aqua-car park out of Manly Cove and the jetties swallow up the blue harbour. Count the boats...
