If the Police want to be picky the guy could also nabbed for riding his bike on a road related area (nature strip) without a helmet...
.... and on footpath, as well as intentional loss of traction, but he's careful rider having only lost his licence twice for street racing.
We have to deal complaints from the community about these
mental giants every week or so, they're generally unlicensed, unregistered, under age, unroadworthy, at least this guy isn't as stupid as some.
