Speed limiters on new build cars

[dakta]

Depends what circles you're in

Really wish it was as specialised as it used to be - often it's just a value in flash memory that can be updated with clone kit off eBay

It's like having your playstation chipped these days

my limiter is a pain (Thanks Peugeot). You have to click the thing 10 times to change 10mph. Why. Are there any 35mph speed limits? It is an old car tho. one click for each 10 mph would do it.

If you hold the button it should increase/decrease in intervals of either 5 or 10mph.

Mine does that, it takes 3 seconds for each jump, I'd rather it just went up/down in 10s.

I will try that. thanks

Lots of 5mph "limits" on private land like car parks. Other countries might have speed limits in fives - the only place I know of though is the USA.

One click being 5mph would still be better than it being 1mph.

1mph jumps are good in cruise control mode if you don't have adaptive, but aren't needed in limiter mode because you can just lift off.

Two uses for single digit increments to a speed limiter setting:

All* correctly working speedometers over-read to some extent. Setting a value slightly higher than the limit can be used to compensate.

Driving abroad, so you can set the equivalent of a kph speed limit using mph units, or vice versa.

* Under-reading is not allowed. Perfection is allowed, but very unlikely to exist.

No. First point is you can actually do 77mph. Second point is there are situations where going beyond such speeds is acceptable (taking someone in your vehicle to A&E in an emergency, for instance) if the road and conditions are suitable. Third point is where do where the line is drawn with who doesn't need a limiter. Fourth point is vehicles that produce co2 are going the way of the dodo anyways, so what's the point? Fifth point is criminals and people who aren't ones for following the rules of the road, will find ways around such limiters anyways, so again, what's the point?

Emergency services, the aforementioned reason, fleeing from a life endangering incident, overtaking a

Do you think that all new cars should be fitted with a speed limiter of 75mph from the build? The two main benefits are obviously improved road safety and also reducing pollution/saving fuel as a result of vehicles not being impacted so much by air resistance and lower revving of the engine.

I think 70mph would be a little too low as sometimes people need to speed up and go above the road limit to get out of the way and avoid a potential accident, so 75 or 80mph would help in this way. However, there is no reason anyone should be travelling above 80mph, so why not have speed limiters on all new cars for the reasons given?

There are roads within 35 miles road miles of my home that have a legal speed limit of 81 mph 130 km/h, can those of us that live in Kent have our limiters set higher? (like our trains)

Any mandatory limiter would need to be 130km/h as that is the normal motorway limit on the mainland. I don't think there is anywhere in Europe where there is a higher limit (Autobahnen are advisory 130).

 

[paul1609]

It's 140 km/h in Poland and possibly others.

 

[Bletchleyite]

Well I didn't know that. If it had to be 140km/h it would be basically useless in the UK, because very rarely do you see someone doing over 90mph on the motorway anyway.

Should a speed limiter also have rain/moisture sensors to recognise the reduced 110 km/h 'wet weather' limit in France? For that matter, has anybody ever found the applicable definition of 'wet weather' ?

In case its not obvious, I do have concerns that some drivers will misunderstand that the mandated systems are 'Intelligent Speed Assist' and expect these systems to do all the work.

Increasingly the likes of "smart motorways" will define that by showing a limit.

 

[Trackman]

Another thing to think about is what about those of us who do track days etc.? Clearly a speed limiter would render them a bit pointless. Why should we be penalised because some people can't stick to the law and drive at the speed limit on the road?

Some performance cars in Europe do have a top speed limiter (some daft top speed) but the GPS can suss out when it's at a track and switches it off.

Is this still a thing? I knew there was a trial a while back.

I believe he means 35 miles away by ferry

lts not a trial A16 & A26 once outside the Calais area.

hahaha! Didn't think of that!
But they did some years ago trial a 80mph speed limit in some outside lanes of motorways in Kent.

You obviously don't go on the M6 Toll Road then.

 

[philthetube]

Any decent software engineer with a laptop would be able to 'tweek' the limiter in seconds just like they remap cars (including mine) at the moment.

And anyone taking advantage of this could be subject to a ban.

I think they should be introduced though my reasons are different to any other mentions on here. They would cause reductions in crime as capturing criminals would be much easier.

or the M40 in Oxfordshire / Warwickshire, or the M6 north of Lancaster!

We discussed the pros and cons of this in your previous thread and I think we came to the view that the technology was nowhere near foolproof enough at the moment

Speed limiters in cars

Incidents like this make me wonder if speed restrictors in cars, h=to hold cars to sp0eed limits should be introduced. https://www.railforums.co.uk/threads/ecml-level-crossing-incident-13-06-21.218643/ This would greatly reduce car crime and save lives on British roads. My instincts are...

Outside rush hours, add the M5 south of junction 3 to that list too.

IME drivers speeding at 90+mph is pretty common on any motorway or NSL grade separated dual carriageway where the traffic is free flowing enough to allow it, to the point I would regard driving more than half hour or so along such roads and NOT seeing it as unusual.

depends on the camera situ. Plenty of those on the M5 south of J3.

I think it's a lot less common than it used to be, especially with petrol prices being the way they are. Anecdotal obviously, but last time I made a long motorway journey a few weeks ago I never went above an indicated ~75mph, and hardly anything overtook me, which I thought was unusual

Fair point, IIRC there are variable speed cameras between J4a and 6 then again around Bristol.

It does vary admittedly but in my last long distance drive, to Swansea (M5>M50>A40>A449>M4) 6 weeks ago, there were definitely a few cars which zoomed passed me when I was cruising at 65-70mph. I make the short hop from J3 to J4 of the M5 2-3 times per week on average, not uncommon to see the same there too.

None of this will change the fundamental thing - that most people don't care about the environment, fuel efficiency or the effect that their speeding has on others, etc. Limiters will be disabled by idiots who think it's clever to drive fast, etc. There will always be those who bleat about their human rights being curtailed because they cannot do exactly what they please, when they please, where they please. The behaviour of people in their cars is a sure-fire indicator of the sort of people they are, and it's usually very depressing.

but most people will care about fuel economy because that equals money!
