" Just take a look at the average engine size and bike size in Canada vs. Europe."

Good point. Our best selling brand (HD) is all about huge, heavy bikes that take up a lot more space than the average European Supermoto, Dual Sport or Sport Bike. Lane filtering with a 450lb., 650cc BMW makes a lot more sense than lane splitting with a 850lb HD Electraglide that's twice as wide, 50% longer, and gets the same kind of mileage a car does.
