can hold a tractor? sorry i don't see many people going fast or crashing in tractors, just saying its not every day you'll see a farm house tractor cruising in normal traffic they're too SLOW. Also, i ride hard and if i can rip up concrete from a stack im pretty sure i'll rip up hexagons too, and also you gotta think of the kids, if i ever have kids imma teach them how to piss off the neighborhood and rim ride their bmx's up and down the street, and i'd rather them rim ride and rip up sparkz on the concrete rather than glass hexagons, what about people walking around the corner to the swimming center? walk on glass bare foot in 42 degree(I'm Australian) weather?? ahahahah yeah theirs a good reason to sue the councils, glass hexagons bloody gave the bottom of peoples feet 3rd degree burns, great job. Its a stupid idea, good luck getting grip on the hexagons to, will be more car crash deaths than ever before if they actually try this idea..
