That's the key, if the repair or replacements were relatively cheap, this thing would take the fuck off! I don't see those wheels taking much damage without needing replacement, but the technology itself is viable, we need to develop tougher materials that can withstand such speeds (100mph), you're looking at the future! 360º rotation, no more parallel parking, holy shit this is awesome! Carbon nano tube tires, Kevlar, who knows, but this is the system that'll use it!
