Motorcycles would be the coolest thing ever, except for the fact that people die on them all the time. I think more people in my life have died from motorcycle accidents than anything else. You can be the best motorcyclist in the world, but that doesn't stop an old senile lady from crashing into you on the highway.
And they're not very practical. You can't really go grocery shopping, or haul anything with them. And if you need to give more than one person a ride somewhere, you can't. And not to mention how crappy they are to drive in bad weather, which is like, 50% of the year.
But whatever, if my friends get a motorcycle, I'm at least getting a ride.
