I'm not sure how to feel about these people who ride their motorcycles all winter in cold, icy climates. It seems like poor decision making, an accident waiting to happen. Though, to be fair, people who walk everywhere probably say the same thing about me when they see me pedal past them on my bike in the midst of a snowstorm. But, to be extra fair, those people are correct. Through the transitive property, according to my calculations, I'm correct in saying that it's a bad idea to ride your motorcycle in the middle of winter when there's ice all over the roads.
