Pipewellgate Car Park

Pipewellgate car park. Head down to the right of the Hilton and follow the road around until you reach the river beat restaurant. Take the left and go under the bridge. Keep walking and you'll walk past the old Gateshead sea cadets corps building. Car park is against the river. Can't confirm is this is an actual dogging spot. Sunday night I was down and saw a lass giving a lad a blowjob in a car. Two cars one was empty. Couple other cars showed up. What's the etiquette here does anyone know? For walkers?
