In Australia for the first 12 months newly licensed riders are restricted to embarrassingly low-powered motorcycles (250cc) and must display a bright yellow L-plate at all times. So when the owners of extremely high-powered bikes (650-1000cc) returned to their vehicles to find an L-plate, they immediately felt the embarrassment of being a learner again. On removing the offending material they discovered a message implying they lacked the experience and nerve to take on the world's fastest street bike, the Suzuki Hayabusa.
