This rapidly decreases the following distance when the lead pulls away,
resulting in an early demand for acceleration.  This is helpful because the
MPC often stops ~4m behind the lead.  Meaning the lead has to move ~2m before the
MPC even considers requesting acceleration.
The offset is capped at half the total Stop_Distance, is linearly proportional to
the speed differential between ego and lead, requires the lead to be traveling
faster than Ego, and tapers away to 0 at 10m/s, all for safety and comfort.
If not clipped, it can go negative at higher speeds causing more
distance.

Also if tapering is not last, then there can be a clip-like
transition.
