I see the latest EU dodge is all new cars from 3 years or so hence will be fitted with automatic speed limiters, to prevent speeding. :(
It will be "intelligent" using some kind of wireless link but will not apply the brakes, instead cutting engine power. Initially drivers will have the ability to disable the function, but after a few years of reduced accident rates etc......
It is suggested that it will include a "kick-down" feature so you can accelerate out of trouble.
And of course, the UK is committed to adopting EU regulations.
Luckily it won't be retrospective, so I won't bother upgrading the Sabre Six. :twisted:

Cynically, I assume this is so they can road test some of the driverless car technologies :roll:

Also, I was listening to the radio this morning and West Berks council are to increase the annual licensing cost for taxi's and in turn the cabbies were stating how they would pass on the cost to the punters. I couldn't help thinking, they had better milk it for as long as they can, as when driverless cars are mainstream, they will be out of a job!

Sounds like scaremongering to me - any links?

There is a proposal up here to charge every vehicle that enters Newcastle - buses and taxis included. It seems like they want to turn the city into a waste land. When the shops start to lose money they will move out and people will stop entering the city which will mean no money at all coming into the councils coffers. How stupid are they.

It has been done everywhere else, so it must be a deliberate policy to close down all commerce in town and City centres. It is not possible even for councillors to be quite that dense with so much evidence from previous behaviour.

A not well published fact too is that the rates on commercial property like shops is more often higher than the rent ! But it may get better for shops when internet deliveries are not subsidised by the drivers on 10p per package :D

Interesting original post, here in Australia a lot of trucks/ lorries are speed limited but to my knowledge it hasnt been discussed for cars. Possibly because we have varying speed limits across the States

In Singapore there used to be flashing lights and bells on the vans and lorries which came on if the speed limits for these vehicles was exceeded - made spotting speeding commercial vehicles easy for the police. Don't know if they are still like that now.

Differing speed limits in different places shouldn't present any particular difficulty. In this country at least, all the roads and their speed limits are logged in databases, which in conjunction with a GPS receiver, will tell you your current speed, your location (i.e. the road you're on), the prevailing speed limit for that road, and whether you're exceeding it or not.

It would only be a relatively small step, in modern computer-controlled cars with sat-nav, engine management, and cruise control, to link all that up, and produce a car which will not normally drive over the speed limit. The only thing that might be more difficult is the other kind of "variable speed limit" as used on, for example, so called "smart motoways" :barf: and I'm sure they'e working on that.....

Eventually found a source for the original story - the RAC.

Automatic speed limiters are already fitted to many cars - the forward looking radar that works with cruise control to maintain a safe distance.

What I think you’re referring to Philip, is ISA (intelligent speed assistance) which uses sign recognition (something lots of cars already have - my 8 year old daily has) or speed limits from GPS data (again, available years ago) with the cars speed limiter (also available years ago on some cars).

TBH, it’s an obvious move and I wouldn’t argue against it - personally, I usually set my cruise to the speed limit outside a national area, as soon as it flashes up on the dash. You can still override it and I suspect that function will continue to be available long after we’re gone :D

My new daily has road sign recognition for speed limits but I would not call it good enough to rely on. It’s thought there was a 25moh limit on a stretch of NSL dual carriageway and a 110mph limit in the M6 roadworks.. it does normally get it right but I’d say it only reads 80-90% of the signs.

That’s interesting - I’ve never seen mine get it wrong? I’ve also watched it on the satnag and it’s usually correct within 10-20 metres, although it doesn’t have road works and occasionally has out of date info (where a speed limit has been changed from national to 50 for example).

My SatNav has them as well - I’m on about the camera-based version (same camera that does lane departure in my case). It sometimes catches/reads Smart Motorway overhead limits (I believe the Jaguar system is better).
