Will the motorcycle replace the car for performance-minded drivers?

We ran across an interesting question posed by Paul Crowe over at The Kneeslider and decided to see what our readers thought: Are motorcycles the future of performance? This question seemingly has some merit due to the tighter CAFE requirements that the government is forcing upon automakers. General Motors cannot afford to sell hundreds of thousands of Camaros at great prices, no matter how many consumers want them. Instead, it seems that the highest-performing Camaro could be a hybrid, which would undoubtedly cost more than an SS with a V8 engine. Rumors are circulating that the Corvette ZR1 will be the last one powered by a larger-displacement V8 engine. Motorcycles, on the other hand, have so far slipped under the radar. Although it is probably not necessary since most bikes get pretty good fuel economy anyway, CAFE does not exist in the motorcycle market. Is the performance car going to go down in smoke in the wake of increasing fuel mileage? If so, will speed junkies make the switch to motorcycles?
