cars. In the UK in 2017 there were 116.9 motorcyclist fatalities per billion passenger miles, 61.5 times the rate of 1.9 fatalities per billion passenger miles for occupants of cars. UK data shows a wider disparity between cars and motorcycles than US data in part because it is based on fatalities per passenger mile while US data is based on fatalities per vehicle mile. A national study by the Australian Transport Safety Bureau (ATS) found that: Motorcycle rider death rates increased among all rider age groups between 1998 and 2000 Motorcycle rider deaths were nearly 30 times more than drivers of other vehicles Motorcycle riders aged below 40 are 36 times more likely to be killed than other vehicle operators of the same age. Motorcycle riders aged 40 years and over are around 20 times more likely to be killed than other drivers of that same age. Bicyclists and pedestrians are also unprotected in collisions with cars on public roads. In 2017, there were also 5,604 bicyclist casualties per billion passenger miles or 23.5 times the rate for cars, compared with pedestrians having about 7.6 times as many casualties per distance traveled. However bicycles and pedestrians travel at much lower speeds so the risk they incur per hour of travel is only a fraction as great. In contrast, the rate of fatal accidents for buses is lower than for cars, about 0.83 times as many. The article on Motorcycle fatality rate in U.S. by year indicates that the number of motorcycle fatalities in the US has remained about 5000 per year for most of the past decade. In 2006, 13.10 cars out of 100,000 ended up in fatal crashes, while the rate for motorcycles was 72.34 per 100,000 registered motorcycles. In the European union (the 28 member states) there were 663 driver and passenger fatalities for mopeds and 3,644 driver and passenger fatalities for motorcycles, according to data available in may 2018, although in the UK and Ireland mopeds are counted as motorcycles. The PTW (including both moped and motorbikes) rate is 8.2 fatalities per million population in the EU in 2016. In the EU in 2016, PTW fatalities represented 17% of traffic fatalities, with a range from 4% in Romania to 32% in Greece. More than 88% of those fatalities were males In France motorcycle fatality rates by travelled distance are 2200% higher (that is 23 times higher) than
