Nah dude, shotgun is the way. You're not alone in the back, you have a driver to talk to, which is guaranteed. In the back, you might sit next to someone, but you might not... then you truly are flying solo. You also mighjt be sitting next to someone you dislike, while if you're sitting shottie, there's a pretty decent chance you're on good terms with the driver.
You also have control over music, etc., and in my experience shotgun packs, so you either get firsts or seconds. And your window rolls all the way down for cigarettes, throwing things at people, yelling at people, egging things, not to mention overall comfort. It's the way to go.
