Cars that keep to speed limits
Discussion
Since devolution of speed limits, not all meet the guidance for the type of road, so not necessarily safest.
Quieter streets may be better than safer ones.
New EU technology in cars to keep to the speed limits.
Would it create dozy drivers?

Our Focus has a speed limiter option - set a speed and it won't accelerate past it unless you floor the throttle. Simple enough and does it's job.Quieter streets may be better than safer ones.

If it helps those who claim they're spending all their time watching their speed to avoid being caught and not enough time watching the road, then go for it :-)
Found this warning feature annoying on a 20MY BMW 1 Series, heading down the A9 there's 50mph signs that apply only to HGV's yet the car flips out every time when doing the car speed limit and comes across a sign.
People will just get even more complacent if they don't need to moderate their speed and due to the public now associating not speeding with safety accident rates will increase.

On my Mercedes you can set up the auto driving function to accelerate and decelerate to the signed the speed limits, as well as doing the steering too.
I've said it a few times, but in continental Europe, the software has worked flawlessly. In the UK however, I've had a number of near misses. I don't fault the technology, but the poor infrastructure and bad signage, especially temporary speed limits.
To give a few extreme examples I've run into.
Just a few from me.

To give a few extreme examples I've run into.
- On the M1, there is a slip road which runs parallel. The speed limit of that is a 40mph. That sign is clearly visible from the motorway as the lanes are practically side by side, with the hard shoulder and tiny barrier splitting them. If you are in the left hand most lane of the motorway, my car will read the slip lane speed limit and break sharply from 70 to 40. This sign shouldn't be visible for motorway traffic, but this has happened a few times in other places in similar situations.
- I have been overtaken by a highway pickup with all it's signs in the back. One of which had a 20mph sign. Again, my car read this and borderline did a near emergency stop. Has only happened the once, but very scary at the time.
- Temporary speed limits often don't use the correct sizing for speed limit signs, or they don't bother putting an end of speed limit sign up so the car wont change speed correctly.
- On managed/"smart" motorways, often when the speed limit is reduced to say 40, the car adjusts fine. You see in the distance one of the gantries changes to national speed limit, but once you get there, the sign has just vanished completely and is just blank. As the car doesn't see its national speed limit sign, it'd keep you at 40 until it next see's a sign. Again, poor design, IMO smart motorways should always just show the relevant speed, and arguably in this case the speed limit is still 40 as not told otherwise.
Just a few from me.
We all know that in the plan is to get everyone into shared self driving cars, my guess is that to facilitate this change there is going to be a push to make driving either completely devoid of pleasure or to get the general population to see driving your own car as reckless and inconsiderate.
Do these systems use cameras to read speed limit signs or rely on databases linked to GPS locations? I tend to find Google maps can be pretty poor with speed limits, and never gets the ones that are different depending on the time of day. Then you have the French limits that change depending on the weather...

Our one litre Skoda Karoq has a speed warning function - currently set to 160mph, which amuses me if no one else. RizzoTheRat said:

They read.The forward facing camera(s) in the windscreen are used to detect speed limit signs, as well as no overtaking signs and will use this as the primary source. Where no signage is visible, data from the navigation system is used.
Ultimately, the driver is responsible though!

My Merc got speeding ticket when it set to Distronic with' follow speed limits ' on. I've said it a few times, but in continental Europe, the software has worked flawlessly.

Limit dropped to 90kmph on the approach to south side of Bordeaux ring road coming from Toulouse. As I approached the speed camera the car auto adjusted speed down to 90 kmph. Just metres before the camera the car speed up as it figured the limit was 110 kmph, but on the exit that I wasn't taking! ... I didn't realise in time what was happening, camera flashed and 45Euro ticket arrived a few days later.

My Alfa GTA has a warning that was originally set to trigger at 85. Every time I did more than 85 I saw the warning flash up out of the corner of my eye, and was convinced it was an oil pressure warning flashing up. Problem solved by setting it to 110.rscott said:

My Mondeo has the same. I like it a lot more than Cruise Control. It requires you to be more involved, as you control the accelerator pedal. Set it, then adjust it in 5 mph increments with the steering wheel buttons, or knock it on/off as you feel like. I don't always use it, but it can be useful in just giving you that "dead throttle" feeling when you start to wander up to the set limit. Ans as you say, if you need some grunt sharpish, just bury your foot in the carpet and the limiter knocks itself off until you let the speed fall to match it again. It means you always feel like it's you who is controlling the car.If it helps those who claim they're spending all their time watching their speed to avoid being caught and not enough time watching the road, then go for it :-)
I couldn't bear abdicating control to a camera and/or GPS map. I don't even like using cruise control...
