Newly trained drivers aren't the problem, nor is their education IMO.
Blanket statement Marc, and it lacks credence.  Kinda like getting basic
flight instruction before becoming a stunt pilot.  You have basics in
advanced training that require knowlege and experience first.  You can add
crisis training ANYTIME in the driving process.  As a rule, it's better
assimilated when the NEED for it is better understood.  Safety systems aren't
the end all, but a good start.  I disagree that initial training should
include crisis training.  How about education of car control.

Your street car equipment compromises don't make you that good all the time.
No one is that good.  Period.

If a car has ABS, it's braked differently in a crisis/maximum situation than
one without.  This argument created a huge re-education of police departments
by chevrolet when ABS was added to impalas.  All those tricks you learned,
just don't work as effectively on ABS equipped cars.  So, do we teach newbies
how the "old school works" or do we teach the newbies how to be effective
drivers in the context of what they will be driving (hardware/software).
Hmmm.

ALL the time?  I don't think so.  ABS allows maximum braking effectiveness
and control to be retained with less training.  Specifically, less skill.
Bad?

Beginning drivers have to start somewhere.  Give them experience, any
responsible parent can give them the specific training opportunities for more
when it will make a difference.  Your original point is lost, because you are
trying to teach hi performance driving techniques to inexperienced drivers.
ABS requires less skill in a crisis situation, that's good for newbies, not
bad.

See above, you are thinking old school here Marc.  ABS requires the training
be on an abs vehicle.  It should be since 90+% of all vehicles now have some
sort of ABS.  All manufacturers now have no option for ABS delete.  Why are
you advocating that someone learn non ABS driving techniques on a car with
ABS?  In a crisis situation, I'd want the kid trained to react to the
situation with the hardware and software he's got, not what he doesn''t.
What good is that?

>>Good training increases awareness, increases your lead time on

With ABS that can be taught.  Put another way, you don't have to do any
training in the braking component, since a lead foot stomp will yield the
same (or better) result than any manual modulation.  Stamp the brake, look
for something smaller/softer than you.  Sounds pretty simple to me.

I think that's the biggest hogwash I've ever read, sorry Marc.  I can see ABS
being a problem on massive weight variance vehicles (like empty vs laden big
rigs).  I don't at all see what you describe above (maybe 1970's car abs) on
any street car (geez, even GM's grandam has better abs than that).  If ABS is
impending lockup by definition, then you aren't locking the brake, if you
aren't locking the brake, how does it give a skid.  Maybe Keith can take you
up on this issue.  You've completely lost me in concept and vision.

This is a basic misunderstanding of ABS and traction.  I encourage you to get
some of the algorithums, and listen to what Keith might say on the subject.
I'm incredulous that anyone would think this way of any modern automotive ABS
application.

It's what we have.  Is it a problem?  I don't think so.  Are better solutions
available.  Sure.  Then advocate that parents share the responsibilty of
educating their youth.  Don't give that to anyone but those that specialize
in that training.  For C/E situations, you don't want that specialist giving
baseline drivers ed.  This is a system that's in place and available to
anyone that feels it's importance.

Scan, Identify, Predict, Decide and Execute.  I went on the driving
simulators in 1975, with movies, including ones with cars pulling out, kids
running after the ball, etc.   That was 25years ago.  I'm not with you, e
xcept maybe your defiinition of "detail".

All levels of training is available, prereq?  Driver license.  Mandatory
before?  That's a huge jump Marc, and the logistics and implementation seems
"overwhelming".  How about a simpler system of advanced education credits
tied to insurance rate reduction.  Seems much more reasonable in expectation
and execution, and eliminates the need to revamp a million drivers ed
programs that do an adequate job of education.  I don't want the physed
teacher, or even the basic skills teacher spending time on advanced
techniques.  There's places for that, and a time....

I'm all for opinions if you take them to an advocacy and solution
orientation.  I don't/can't agree that what we need is better drivers
education at the newbie level.  I will agree that advance drivers education
can benefit a newer and older driver, and advocate that parents and their
kids see this as beneficial to themselves and their loved ones.  To advocate
that further, putting money into the insurance companies that recognize that
advanced training reduces claims.  There are several that already do that (I
remember Dominos pizza delivery guys got it).

BTDT, too many turns for me to feel safe at the time, or maybe it was more
the folks that had all the experience....  BTW, in your fwd "understeer"
scenario, you can have lift throttle oversteer, but if weight shift is
significant enough, you can have lift throttle understeer as well (weight
shift forward overloads the tractive abilities of the front tires in a turn).
