Interesting numbers indeed...
But to really understand them they must be put in context to the population of each represented country.
Australia: 812972 kms / 21394309 inhabitants / 0.038 kms per capita
Canada: 1042300 kms / 33357200 inhabitants / 0.031 kms per capita
USA: 6430366 kms / 304969000 inhabitants / 0.021 kms per capita
Spain: 681224 kms / 46063500 inhabitants / 0.015 kms per capita
France: 950985 kms / 64473140 inhabitants / 0.015 kms per capita
Japan: 1193000 kms / 127690000 inhabitants / 0.009 kms per capita
Brasil: 1751868 kms / 187550000 inhabitants / 0.009 kms per capita
Russia: 854000 kms / 141888900 inhabitants / 0.006 kms per capita
India: 3383344 kms / 1137214200 inhabitants / 0.003 kms per capita
China: 1930544 kms / 1325749000 inhabitants / 0.001 kms per capita
So Australia and Canada, statistically, have the least amount of people per km of roadway. While China and India are where you're most likely to get stuck in traffic
But of course, if we consider that in Canada there's only 5 to 6 riding months out of the year, while Aussies can ride almost year-round... I guess that would make Australia the best motorcycling country
Cheers,
Lucky
