Cars have their uses, such as toting lumber, mattresses, dogs, more than two people, or one gimpy one, and they might make sense when it's snowing. But as everyday personal transportation, cars suck. They isolate you from the world around you and from information about what's happening in traffic. It's harder to see past vehicles, and some close stuff (like motorcycles and pedestrians) can be obscured. Besides sucking up more petro-swill, cars are generally harder on the environment. If everyone who owns a motorcycle and could use it to commute actually did so, it would make a dent in traffic problems.
