That's exactly right. I would even say go out and ride dirt on your road bike.
In the end it's about staying loose over the bike. Don't grip it like Frankenstein. Relax and let your body correct its balance when the bike turns, slips out a little, hits a pothole, rock, or does any of the other things that bikes are known to do. There is absolutely no reason that a rear tire skid should be the cause of a crash except in the most extreme circumstances.
