If you can't tell where you're aiming the car, or what you're driving the car on, you're already putting yourself and others at risk. You're trying to make this too broad of a scenario. The bottom line is if I'm going to swerve 5 feet to the left and there is clear open road in that spot, it isn't a risk. If you want to try to throw roll over crap into this, those occur after a driver over re-corrects. If all you do is swerve one way, it's almost impossible to make the car roll over (unless intentional, or an abrubt change in road surface is experienced). When I refer to as driving within my limits, it means doing something less than what the car and / or I am capable of handling, not doing everything right at the edge. Yes there's always exceptions to this, but those can happen any time, any where, such as when my stainless front left brake line popped on me when I was getting ready to make a left hand turn last year.
