A tip for those peeps who do tend lose it; on a rear wheel drive car, do not try to put power down whilst you enter the corner. Brake whilst on the straight before the corner, foot off or feather into the corner, power on out of the corner, but always gradually relative to the conditions so not too hard when it's wet.
Sounds noddy and I don't mean to insult anyone but most people only ever drive FWD cars when learning and don't immediately know what to do in a RWD when they get one.
