Don't count on that. If the person behind you were to swerve while hitting their brakes, that means when they hit you, the nose of their car will be lower (easier to get under your back end to lift it) and have extra traction due to the braking, plus a sideways force to kick the back end of your car to the side. If the rear end of your car loses traction at 65mph, there's a really good chance you're going to spin. Good luck counter-steering out of that one.
