Some railroad reg. requires a passenger train to decelerate with a
jerk < 2 m/sec^3. Don't how or even if they do it on trains but it's
a good idea to keep the jerk down when passengers are out of their
seats and walking to an exit.
It could be done automatically on public buses to reduce tumbling down
the aisle incidents. It would also reduce the multi tasking load on
bus drivers trying to pull out into heavy traffic before passengers
are seated..
The brake pedal would have an override, i.e., stomping all the way
down, in case a pedestrian stepped out in front of the bus.
The number of elderly will soar along with fuel prices so this will
save a lot of lives.

sounds dangerous. trains don't have to deal with other traffic.
you should try this on a simulator, perhaps the TORCS software could be
modified to emulate with your constraints.

IMHO, the location of the jerk is the driver's seat, so that's where
you want to be removing the problem.

A bus can operate at up to 200 passenger miles / gallon.

The jerk could be restricted a lot and the responsiveness would be
undetectable to the driver.
This is before over rides in the braking system.

It's much faster and easier to ask the math folk for some spline

You were against high jerk aircraft and now it appears you oppose low
jerk vehicles.
You get one more chance:

High velocity doesn't imply high acceleration and high acceleration or
deceleration doesn't imply high jerk.

Some of the highest jerk is lateral at least in the front of the bus
when the driver turns esp. pulling away from the curve. The front of
the bus it typically where passengers are walking just after
boarding.
The steering could also be controlled with very little impact on
driveability.
Over rides, of course, in the steering and braking are easy to include
in the overall system.

Newsgroups have charters. Newsgroups have recommended guidelines for
posting. The first guideline, is post to only one newsgroup. The
second guideline is if the topic of discussion is really also germaine
to another newsgroup, then add another one. If you go over 3, you are
a spammer.
You had no idea what you were talking about in jerking aircraft or
ships apart, and only continued to post, contradicting yourself with
every other post, as long as anyone replied to you. This albatross is
hanging over your shoulder.
Reducing / controlling jerk in a multiton passenger vehicle is NOT a
topic for alt.g-w. So you have to be looking for emotional "stokes".

Legislators smetimes overreact. After a disastrous train wreck at a
grade crossing, one Western state passed a law requiring that "When two
trains shall meet at grade, each shall stop until the other is out of
sight." The Governor vetoes it.

yes, but high jerk implies high acceleration;

surely in stages of development.
