More importantly, the change in acceleration or deceleration is linear,
while the difference in total speed change is exponential.

I should clarify what I mean, since the way I wrote it seems a little
confusing:

The changes themselves are both linear, but the *consequences* (in terms of
distance added or removed) is exponential when changing the speed.
