While it is pretty, it is definitely more 'porn' than information. Some information is from 2007, some from 2008. Total fatalities is for a different range of years than total injuries (and is it 100 million motocycle miles or, all miles?). It's hard to know if the total fatalities for motocycles adds up between the bar chart and the spoke graphs (the wheels). It's impossible to know if the injuries/fatalities are high or low compared to car injuries/fatalities (are you more likely to die on a motocycle?) Same with the helmeted/non-helmeted percentages - would be nice to know percentage of people that wear helmets (so one can get a sense for whether you're more likely to die without a helmet). Still, it does look lovely. @Jake,

I feel like there's a clear agenda (making the point that motorcycle accidents are less frequent than commonly believed). Was that in the bar chart in the top center, there's two categories "Motorcycle" and "Motorcycles". I don't think that these categories actually represent different things and should indeed be merged. That would put "Motorcycle(s)" fourth, behind the "4-Door Sedan" and before "Other Vehicles". Am I seeing things here or is there a good explanation? Is it just my paranoia? I’m a bit suspicious about this chart.
