Loose shopping trolleys in the Woolies carpark

Browse Source 
18 kg of chrome chaos each: procedural basket + handle + castors on a
low-friction RigidBody, so they roll away when nudged and FLY when hit at
speed. Four strays around every trolley bay plus five rogues claiming
parking spots, as is tradition.
