Australian Cops Not Happy About Picnic Table Posse [VIDEO]

In the Flint area it is not uncommon to see people on bikes, people  pushing shopping carts or riding a lawn mower for transportation. However, I have yet to see anyone riding a picnic table around here. Not the case in Australia. Police are on the look out for the 'picnic table posse'.

Police are concerned for the safety of those on the picnic tables and other motorists. I have it hard to believe they have not caught the PT riders yet. How fast can those tables possibly go?
