It's not about RWD "being driven correctly" its being able to drive it at all.
I'm the first to admit if I lived on a perfectly flat road with an open, flat car park nearby I'd be the first to go mess around and have some RWD fun, absolutely! But no matter who you are, I promise you that my 330Ci will not get out of our drive unless you fit winter tyres or snow chains - and for that reason, it is hopeless when it snows.
