Well, as for the back sliding out, it all depends on how well you know your car.
I absolutely prefer RWD. Better balance, better on the brakes, easier to work on, better handling (goes with balance) easier on the tires, no torque steer, less or no understeer, and the joy of being able to kick out the ass end if i so desire
Most vehicles are front wheel drive for "safety" reasonson. Such as the fact that the average person is stupid and couldn't figure out how to handle their WWD one, let alone RWD. Also, i believe their is less drivetrain power loss on a front wheel setup. I dont live in an area with snow, and pretty much no rain either, but in my jeep i can have very serious problems getting started when their is anything on the ground (water, leaves, loose dirt), especially if i am going uphill. I imagine if i lived in the snow, i might prefer a WWD car just for the huge amount of weight on the drive wheels...but i dunno. A lot of it is personal preference though. There are certainly a few cars i wouldn't ind driving/owning if they were just rear wheel drive though....
