A study undertaken by the Queensland University of Technology Center for Accident Research and Road Safety in Australia has determined that scooters are safer than mopeds and motorcycles.
Moped as we all know are very dangerous despite the fact that they don't go very fast. Limited to 50cc, and often limited to 50 kph, they can not go fast, but they are very mobile and dodge in and out of traffic, as do motorcycles and scooters. But mopeds are ridden by youngsters with little or no training and experience, so that if the study shows they have the biggest accident & mortality rate, it's no surprise.
But according to the Australian university study, scooters are better off than motorcycles. When they are involved in an accident, 1% of the scooter riders will die, while 3.4% of the motorcycle riders will buy the farm.
According to the report, "Scooter riders also exhibit safer behavior than motorcycle riders, despite both groups meeting the same licensing requirements. This suggests a difference in attitude which sees motorcycle riders taking more risks on the road."
Ergo, motorcycle riders are more aggressive and dangerous, scooter riders take more care on the road.
