Both defensive and fun! I got really good at rear wheel drive when I lived off a dirt mountain road in western NC with my 72 beetle. Yes I have put it in the ditch several times. I banged up my fenders a few times, and it was well worth it.
I drove a FORD 350 Van several years for my company. In the rain under hard breaking the rear will break loose. Being able to control that while coming to a stop saved an accident or two.
I also can shorten my U-Turn radius with my pickup being hitting the gas and counter steer. Usually a very precise move just not appreciated by passengers nor cops.....
Here in SC I am going to have to wait for a snow or an icing once I get my car back from NC just so I can learn how to "really drive" it under adverse conditions. I did drive my aveo in really adverse conditions last year. I was going from Iowa to NC when I got stuck on the WV turnpike and spent 12 hours there. Before being stuck between Kentucky and West Virginia I was averaging in 40 to 50 on fresh snow. The little aveo did really well. I never really pushed the car just kept to conservative survival driving.
