- Some thoughts:
-
- 1) You're already in neutral so the clutch doesn't do anything significant.
-
- 2) If the impact were instantaneous, the brakes would not help. In
- fact they would not slow the car much within the first 1/10 sec. So
- one should not expect them to reduce the initial impact even in realistic
- cases.
-
- 3) Applying the brakes will push you hard forward after the impact, and
- the steering wheel is not as soft as your seat.
-
- 4) If there is cross traffic to worry about the brakes are important.
-
- 5) Perhaps the most dangerous possibility is that your seat back will
- collapse, allowing your neck to collide with the hard rear seat panel
- which is sometimes being pushed toward you by the other guy's bumper.
- (This is a common cause of paralysis). Pushing the brakes increases
- the force against the seat back a little.
-
- 6) As you accelerate backwards (please no flames) you will be off
- the brakes anyway. So the question may be moot.
-
- 7) If you have time to do that, you have time to lay across the front seat.
