This being rec.autos.4x4, perhaps the following analogy might help;
since my vehicle has accelerated to highway speeds and decelerated to
a stand-still many many many times in the past, I see no reason to get
all worked up over the possibility of anything different about it
decelerating from highway speed to zero very quickly when I run it
into a bridge abutment.
