And why do you say you can't brake? If you're going 90 mph, you can brake all the way down to 2/3 of that speed (~30 mph) before worrying about engine dying. That should give you plenty of time to make your maneuver to the side of the road. I would argue that going 90 mph is less safe than the CSC failing at highway speeds.

Not to mention, I can't even recall any incidents where the CSC failed completely while driving. Most people come out to a mushy pedal when they get in the car.

I guess my point is that there are other things to be more concerned about failing while on the highway. The CSC failing is going to much more manageable than some more common scenarios.
