Speed/rev limiter.

[SFB]

Having just read Fidgit's thread about his speeding fines, I'm wondering why in this day and age of electronic devices fitted to cars, that no manufacturer has yet thought to fit a speed/rev limiter that's adjustable to any given speed you set it for?

F1 has it fitted to their cars for the pit lane, so why not any car?

cruise control
driver with the ability to monitor the numbers by the needle

I think SFB has a good point, but so does Custard. If you can't monitor your own speed then are you really capable of being safe on the road?

Plus cruise control has been linked to no end of accidents when people forget to switch it off or get complacent about it and lose concentration when driving. Don't forget as well with some stretches of road having so many different speed limits on it you'd be spending all your time setting and resetting the cruise control. It would probably be easier to just use your right foot...

My Big Brother forecast for the future is that we WILL have speed limiters in our cars and they will be controlled by road side transmitters. So when you enter a 30mph zone your car will automatically be limited to 30mph, and same again for 40mph/ 50mph/ 70mph etc.

Brave New World indeed.

My Stilo has a speed 'limiter' that you can set whilst you drive along. It sets at say 30mph, and once you go over that pings and beeps at you whilst also flashing up a big warning message on the dash telling you that youre going to fast.

Quite a good idea really, especially if you drive in areas that are notorious for lots of speed cameras.

end up with mad max style wastelands outside built up areas

it is very easy to limit the top speed of cars, they do it in japan, and some of the cars in the eu are limited to 155mph. is 155mph acceptable? no, you go to jail for it, so why sell cars that can do it? all cars should be limited to 80mph if high speed driving is really a problem. if it isnt such a big problem that cars should be limited then how can you justify a custodial sentence?

Jug, I think SFB was suggesting a driver adjustable limiter that could be set so that you don't go over the speed limit in areas that require concentration on the road rather than the speedometer. i.e. you see a 30mph limit sign so you set the car to 30mph, 20mph in a school area, 60mph on a single lane national speed limit etc.

 

[custard]

but if you have the sense to set a limiter then you are aware of the speed requirements.
on a m/way i can see it but it can then be too easy to zone out.had a mate had a big m/way smash as he 'didnt see the roundabout' and he was on CC

True, but in many built up areas the speed limit can vary wildly in a short space of time. But that means you spend more time trying to set the limiter so are removing your concentration from driving. It's a no win situation!

wonder how fast a speed limiter would stop you if you were doing 60 on a country road then entered a village which is a 30 zone

 

[jug]

at exactly the same speed as taking your foot off the accelerator, a limiter only affects fueling and/or ignition (usually fueling) so it cant stop you very quickly.

to be pedantic the rate or retardation would in reality be slightly less than taking your foot off the accelerator because there is less intake restriction with the butterfly valve open.

so if it was a small village you could break the limit throughout lol

With ever increasing numbers of sat nav devices being used (& built in to new cars) I wonder how long it will be before we see fines dished out based on satnav positioning?
(not just speeding but parking - these units can pinpoint you very accurately & would know when you're parked where you shouldn't be.
(Alternatively, I also wonder how long it will be before MOT stations start dropping little black boxes into our cars which then activate transcievers built into lamp-posts?)

That's kind of what I suggested earlier

sat nav can not be used to locate your car, the sat nav receives signals from GPS satellites, it does not transmit anything, it doesnt even have a transmitter.

gps accurtacy is 5meters so the parking idea is also not possible yet. someone has built a new system that is claimed to be 0.5m accurate but it is just a claim at present.

tracking transmitters will be fitted to all cars one day, what they are used for is diffuclt to predict, but i would assume speeding will be included eventually, its bound to happen.

.

100% sure about that?

When you look at mobile phone technology, how difficult would it be to incorporate a transmitter into satnav devices - and has it already been done (just waiting for the big switch on)?


1986, I know you did, I was just going along the lines of the device being used to send out fines rather than activating limiters.

Mind you, I think there may be a time in the not too distant when we will all have microchips implanted under our skin (like the ones for dogs) which will be used as identification - you want cash? stand by the machine & enter your pin. You walk in a shop - you register as a customer (you rob the shop & the police come straight to your door). Claiming benefits? With only one chip you can only get paid once (no chip, no money). Want fuel? as you pull alongside the pump it reads your details & when you enter your pin it will allow you to fill up.
Expand the tech a bit & your movements could be tracked via lamp-post transcievers. If the need arose (burglary, mugging, vandalism etc) the police could access the data & would know who was in the area at the time.

[sludgeguts]

I know. Although it seems like we're heading towards an Orwellian future, I have to say that I can agree with some sentiments.

 

[maddogmorg]

another thing is with a limiter what if say you need a little bit extra speed to avoid something? maybe if it's just a buzzer which is activated when you exceed the set limit so as to avoid keeping a constant eye on speedo. but what's wrong with just using your eyes? i'm sure some sat navs already do this?
personally i can tell when i'm driving at 30 etc without looking at speedo just looking out (though i still check just in case), but then i can't do that immediately after slowing down from 60 such as passing through a village as it feels too slow!

 

[StevenRB45]

Surely they'll have to introduce some sort of positioning system for road pricing, although they might just go with cameras literally everywhere. They've had the technology to make speed limiters with gps for ages remember it being on top gear or something similar in a mark 5 escort used gps to locate your position and then activated mechanical limiters to the speed limit
