Car Speed Limiters

BBC News - Speed limiting technology looks set to become mandatory for all vehicles sold in Europe from 2022, after new rules were provisionally agreed by the EU.

I am totally in support of GPS speed limiters, but it throws up more problems than it solves:

(a) Police would oppose as they would lose millions in speeding fines *
(b) Car manufacturers would oppose as they would lose millions in sales of new cars
(c) These speed limiters would easily be disabled by handheld GPS jammers
(d) The 'Jeremy Clarkson' brigade would claim a breach of their human rights to drive like d******ds

And to add would this mean speed humps could be removed?

* UK speeding fine by way of example is 42 mph in a 30 mph zone is 75% to 100% of your weekly salary.

Then there will be the first case when an innocent motorist , trying to accelerate and use speed to get out of a potential accident situation, suddenly hits the limiters............

I'm fairly sure that the police aren't in receipt of fines from speeding. I don't think that limiters will be fitted as it'll be too easy for someone with a laptop to over-ride it in much the same way as a vehicle's ECU can be over-ridden now (so-called "chipping").

My new car already has this. It's not new technology and can be switched on and off, just like cruise control, and also can be overridden with kick-down on the accelerator. As well as GPS map data the car's camera reads the road signs. Bit of a non-news story, really!

This proposal worries me on a number of levels. Most important is that there are occasions when driving on high speed roads where acceleration is necessary to avoid an incident or accident. If you're already driving close to the speed limit then I imagine that the software won't allow that sharp acceleration, thus possibly in some circumstances causing accidents that otherwise could be averted. This could to some extent be mitigated by setting the limiter at 10mph / 15 km/h over the legal maximum speed limit on motorways.

Just what is going on you "need" to accelerate to get out of situations?

I've been driving for more than 50 years and can't ever remember finding it necessary to accelerate to avoid an "incident or accident".

Perhaps driving to the conditions or at a speed that is not at / too near the limit in the first place might be somewhat safer?

For example, when a driver pulls out from lane 1 into lane 2 where there is no gap, forcing the vehicle which you are alongside to pull out into you in lane 3. Harsh braking can cause an accident as vehicles invariably travel too close, leaving acceleration as the least worst option.

I take it you don't spend that much time driving on UK motorways, with their dreadful lane discipline and heavy traffic? Having noticed your location that's probably the case!!!

Sounds great to me - I'd have to concentrate a bit less on staying below 50mph in motorway roadworks, and could therefore pay more attention to what's going on around me. Same applies on empty motorways, when it's easy to drift above 70mph if you're not keeping an eye on the speedometer.

As others have said, it could be overridden by pushing harder on the accelerator, and could also be turned off completely, so the safety issue doesn't really exist.

I'd like to have this feature even if it wasn't mandatory.

Presumably these will not be fitted to cars manufactured for the German market, since their autobahns do not have speed limits?

It then begs the question, why then build engines that enable you to drive much faster than the maximum speed limit?

After all, if the reason is safety and to prevent loss of life, will they legislate for that?

Roughly 50% of the autobahn is subject to speed limits, and there's no law preventing a German registered car from driving in the rest of the EU. So presumably you're wrong.

How about speed limiters being only compulsory for the high risk males aged between 18 - 25? Aren’t they statistically the ones most likely to be in, or cause a fatal accident, as a result of it?

Conversely, maybe speed increasers could be fitted to elderly female’s cars? Perhaps a minimum of 30 MPH (50 MPH on motorways) I’m convinced the dithering and slow driving also adds to the accident data.

OK, so what happens when you're driving on the 50% that's not restricted? How does the car know how fast it can go? (I am basing this question on the information given out on BBC News this morning which suggested that the limiter would be 'guided' by the speed limits shown on the road signs).

ACC cruise control does that.

On that basis, in areas with no speed limit signs - built up areas where there a re street lights one assumes the limiter wouldn't work. I imagine however that the limiter will use speed limit information that's loaded on to the GPS system, but I doubt that would take account of limits placed using signs stuck into grass verges at the side of the road such as is the case on overnight roadworks on motorways, or works on side roads with road works which often have special temporary limits in Germany at least.

On derestricted stretches of Autobahn I imagine the limiter would effective switch itself off. If the system were really smart it would reduce speeds in inclement weather such as heavy rain of fog; probably a much more important development than a blanket speed limiter

Just to clarify, as I thought fines went to further safety measures!

So Where Does The Money Go?

According to Simon Moon from This Is Money: “I spoke to the Ministry of Justice and the Department for Transport who told me the income from speeding fines goes into what is known as the Treasury's consolidated fund, which is a bit of jargon that really means the Government's own bank account.”

The first I heard was imposition of a top limit to 120.

Our local Road Safety man thought that was the case and cited a case where one motorist had exceeded 150.

He was surprised when the interviewer talked about variable limited speeds. Certainly GPS would enable that.

Interesting that the head of Nissan's autonomous vehicle division (he's ex NASA and used to design planetary probes) says that autonomous vehicles will never eventuate for that very reason. And to support his case he shows videos of motorists' deliberately breaking the road rules (often speed) to avoid a serious accident.

The modern scourge on today's roads is the cocaine junkie on a high with a feeling of invincibility causing some of the worst kinds of accidents. Limiters may help here but somehow I doubt it.

“Speed camera vans in North Yorkshire have been described as “the single greatest underachievement of income” for the county’s police force.

The Press website in Yorkshire says accounts for 2017/18 have revealed that road safety cameras brought in millions of pounds LESS than the force and the Police and Crime Commissioner expected.

Although the force does not receive revenue from fines, it does from speed awareness courses but in 2015/16, the force received just over 1.8 million from the courses, and based later budgets on a similar or higher amount, even increasing the number of speed camera vans on the region’s roads........”

I doubt it too; that sort of low life will buy pre 2022 Mitsubishi Evolutions and their ilk and drive them like maniacs, as they do now. I can see the market in 2nd hand pre 2022 performance cars generally rising considerably to satisfy the desire for speed and the boosting of egos for the inadequately endowed!

Impatient drivers who want to overtake 5 or 6 vehicles in a row,but are then suddenly confronted with oncoming traffic from a blind bend, would probably need to 'accelerate to get out of a situation'......
