I've seen the scooters in the park fairly regularly just near the salvage yard. Got annoyed at first, but I don't think they're actually doing anything wrong (unless no lights) as that bit is almost certainly still legally a road that happens to have two gates at either end of it.
Course, I don't know where abouts your ninja was in the park.
No lights and motoring across the footbridge over the lake. I'm guessing that's not legal. I'm hoping he was just taking a short cut, not cruising for someone to mug.
