What does it matter? There's no purpose for a motorcycle or a sports car either. If you want a truck.. buy a truck. It's their money
Motorcycles are generally great fuel efficient ways to transport one person. Sports cars are great for recreation, but again should probably not be used as your main commuter transportation.
There are these things called fossil fuels, and there are only so many dead dinosaurs left to use in cars for the rest of human existence. Also the more gas consumed, the more exhaust pumped into the oxygen that we'd like to keep breathing for the rest of our lives, and the lives of future generations.
It may be their money, but it's my kids ****ing planet.
