It is not as though the line between motorcycle and car is getting blurry, it is more that line between motorcycle (or powersport) companies and car companies is getting blurry. Honda builds cars and motorcycles, BMW builds car and motorcycles, Polaris builds motorcycles and the Slingshot, KTM had its little race car, Audi owns Ducati and Kawasaki Heavy Industries builds motorcycles and heavy things. At the upcoming Tokyo Motor Show, Yamaha will be revealing its car concept. Little information is available beyond this vague image but the car is said to represent motorcycle ideals. Why not? Everyone else is doing it.
