Have you really never been in a situation where you need to accelerate out of the way of another driver braking the law? For example, driving through an intersection and suddenly you notice someone is running their red light on a collision course. You must either go forward or backward. Much more difficult to reverse than to accelerate.

I check intersections before proceeding through them , so no that hasn't happened in 250,000 miles of driving. And what is that, like 0.5 seconds to make a difference? How much further will the car be when it had this subscription vs not having the subscription?

  Half a second seems roughly right. An exact answer depends on the car's power band and other more complicated factors. You'd expect an extra 2-8 inches, and if the interesection were a bit wider and slower so that you had 1.0 seconds you'd expect an extra 16-64 inches. Also, on such small timescales the engine's responsiveness would come into play, and it's unclear if the tuned package would affect that for sure, but it'd be hard for it not to. 2-8 inches probably won't give you better odds of any meaningful outcomes beyond an extra few percent. 16-64 inches could easily be the difference between a miss and a crash (especially if the red-light runner swerves or counting the selection bias in which distribution of possible strike zones you're likely to have predicated on the assumption that accelerating was a reasonable course of action), or would very likely be the difference between an extremely dangerous collision with the driver's door and something more reasonable toward the back of the car (worse with kids in the back -- thankfully for the purpose of this discussion, only 15% of cars in the US have passengers).
