Snow and ice aren't that bad of an issue for most cars, RWD included.

Snow and ice + Hills or elevation changes, however are a different story.

I've seen numerous MBs and BMWs stuck trying to get up the hills in winter time and I know the Washington, DC area is nowhere near as bad as some of the states up north.

I remember when I was a kid, my dad had to change tires every winter to snow tires. I know no one here wants to have to do that ... and all season tires on a RWD cars just can't cut it, regardless of the hype!
