Chances are thats not going to happen to you on street tires. If you are generating enough grip to lift the insider rear you shouldn't have to do anything because the car is following the arc it is on. As far as not being able to counter steer a fwd car when it slides thats horse ****. You can counter steer anything, generally the correct response would be a slight steering correction and stay in the gas, that will usally pull the car out of a slide.
