Speed limiter wanted

Speed limiter wanted

Does any car come with a speed limiter like this?
I do not want to worry about speeding and would like to be able to set my top
speed to 35 mph, or 55 mph, etc. while driving.
Pedal to the floor and I max 35 mph through small town speed traps.
A long time ago cars used to have a set-able buzzer that would warn you of over
speed.

Many come with cruise control, which isn't the same thing but does the
job and is more useful.

Driving a manual transmission goes a long way. Some of these comments
could apply to semi-manuals also, I suppose.

In an automatic, you can go from 0 to freeway speeds while doing
nothing but maintaining a light throttle. It will shift as necessary
and keep accelerating. Obviously, this is not the case with a manual.

If I'm driving through a park or school zone where the speed limit is
30 km/h, I know that I'm observing the limit, because I'm in second
gear, doing no more than about 2000 RPM. There is a big difference that
can be felt between that and going 35, and by the time you get to
around 40 in second gear, you are pushing it quite a bit and it's
asking for an upshift.

After a while, you develop an intuition about what speed you are going,
from the continuous feedback and integration of the sensations of the
throttle position and sound of the engine with what's indicated by the
instrumentation. So if you tell yourself you're going to go a certain
speed, then you just stay in the feeling for that speed. And, by golly,
whenever you glance at the speedometer, you will find that you are in
fact going at that speed. Moreover, that will cease to be a surprise
after a while.

Plus you are simply more engaged with the car to begin with; your mind
does not drift as much away from the task of driving, so you are more
likely to pay attention to the dash as well as the road.

> Pedal to the floor and I max 35 mph through small town speed traps.

Your pedal could not have direct linkage to the engine throttle for
that to be implemented properly. How do you imagine this working? WIth
the pedal to the floor, you'd have maximum acceleration until achieving
the limiting speed and then suddenly, the throttle would change to just
maintain that speed. Is that what you envision?

Or would you want the pedal to not control throttle at all, but only
serve as an indication to accelerate?

In that case, cruise control will do the job. Use your accelerator
pedal to get to the minimum speed for cruise control and then enable
it. It will take over so you can remove your foot from the accelerator
completely. From there, you can set your coasting speed, or tell the
cruise system to go a bit faster or slower with its controls. I.e the
up-down control is your accelerator, effectively. If you slow down, you
can tell it to resume coasting at the original speed.

If you need that, it means you are not paying enough attention to the
driving. You don't want to speed, but your own daydreaming mind is
allowing you to lose the control that you would like to have. The real
benefit of the buzzer is that you wake up and pay attention.

How 'bout a radar detector? Train yourself to make use of it and you will
also train yourself to frequently check your speedometer. Admittedly, some
vehicles are harder than others for keeping one's speed in perfect check
(like a vehicle that's not your own personal vehicle).

Personally I don't worry too much about what my exact speed happens to be.
It only takes one or two glances at the speedometer while it's at the speed
limit, and after that I can fairly accurately judge my speed while just
watching the road. The only times I have been stopped and ticketed for
speeding were times when I was intentionally and persistently doing so (e.g.
on empty, wide open freeway engineered and built for 70+ mph but which still
has posted on it that obsolete "1972 energy-crisis spawned, and wholly
failed" experiment, the absolute 55 mph speed limit).

I had an idea a LONG time ago, for a radar detector that was integrated
into the car's cruise control, so you set the legal speed where you are
into the detector, and set your actual speed into the cruise, and if
the detector gets a strong alert, the cruise drops the throttle and
coasts down to the legal limit...but even that could have unwanted
safety ramifications, I decided...

Interesting idea, but you're right about the potential unwanted safety
ramifications; not to mention the problem of "false alarms" that a radar
detector will regularly deliver to the cruise control, making it
impractical. On that note, using a radar detector is somewhat of an art
IMHO. One becomes somewhat familiar with the radar detector's beep (and/or
other sound) patterns and such so as to distinguish mere "noise" from the
more likely to be meaningful warnings.

On a tangent to this topic, I was just thinking today how convenient it
might be if the speed limit for a particular stretch of road one is on could
be broadcast (like, in digital form) from short range transmitters installed
in tandem with speed limit signs, to cars equipped with compatible
receivers. The information could then, either, be continuously displayed in
the car's console for the driver to see at any time, or relayed directly to
a cruise control circuit. I was about to dismiss the thought as technically
unworkable given that radio signals will not obediently confine their range
to just the right stretch of road and nowhere else, when it occurred to me
that GPS technology could be incorporated into such a system, rendering the
idea entirely plausible.

Of course such a system, if developed and proven practical for drivers,
would not likely be received with open arms by governments. Why? Simple:
it would cost them revenue. Aside from the revenue they'd obviously have to
spend to implement it of course, it would be perceived by them as a threat
to a time honored source of revenue which bureaucrats and politicians have
long taken for granted as 'cash for the taking': the fines now routinely
collected from countless "law breaking" drivers for (whether wholly
unwittingly or not) "exceeding the posted speed limit".

Yeah you wouldn't want your cruise to suddenly drop the throttle just
as a semi was bearing down on you from behind...

You're right about having to decipher what your detector is trying to
tell you...I always leave mine in the most sensitive mode, which
creates tons of false alerts, but I unconciously filter them out, and
only respond when the signal has that "urgent" sound to it that I've
learned to recognize...drives my friends nuts when they ride with
me...:lol: ...I know where every radar emitting motion detector for
security and door openers in town are...I wondered if those areas are
also problematic for the police to get a useable return on their
signal? Never thought about that, but I've never seen them running
radar traps in areas with lots of ambient radar noise....

I've noticed from driving over the road as a truck driver that there
are some ares (particularly around Chicago) where they have emitters
that broadcast radar detector jamming signals very strongly from boxes
mounted up by highway signs, etc. But as to my previous observation, I
wonder if the police radar is useable in those areas?

The day they put something IN MY CAR that can narc me off for speeding
is the day I quit driving...I know some rental companies and fleets use
them now, and I also know that your ECM is capable of a data capture ala
the black box in an airliner, to record what happened in regards to
speed, brake application, deceleration, etc leading up to a crash...but
that is only used in very limited circumstances where the details of say
a fatal accident are not readily understood, and more info is needed to
reconstruct the events and assign blame...

So I guess it's not that much of a stretch to suppose that they could
(if not already happening) use the data recorded by the ECM to be a
kind of "character witness" to your driving habits, excessive speed,
sudden acceleration and braking, etc. I know that the truck I drive has
a system that logs this stuff so my company can weed out drivers that
are hard on equipment and wasting fuel....

Some trucks in Europe comes with a switchable speed limiter 80 km/h in
combination with an electronic acceleration.

dunno about warning / speed control devices, but using the speed control
should only be done for hiway driving for safety purposes.

new cars at one time had a mechanical governor, not any more.

revving seems to be a necessity at times.

I liked the buzzer system g m had.

driving is a full time job.

see what is in this site that's useful.

Thanks.
Even a simple beeper/buzzer that I could set would be good.
I may be able to come up with something using the VSS.
