My car has adaptive cruise, I’m looking at a ( new ) car which has radar cruise, what’s the difference in these systems, or are they the same by another name?

Same thing, different name. Adaptive cruise typically uses radar to hold station with the vehicle in front, whilst LiDAR is also utilised.

Thanks, I thought as much, I like how my car maintains its distance from other cars in front. I know some don’t like this but I find it handy on long motorway journeys

Yes I agree it makes for a relaxing drive.

And we’ll find as more and more drivers use it that traffic will flow more evenly on motorways as the cars react to changes in speed rather than drivers occasionally not paying attention then over reacting, braking harder than would have been required if they’d have started to slow as soon as the car in front did.
And because some are closer than they should be, that stab of brakes becomes amplified a few cars back.

I prefer the simple old fashioned cruise control. I had half a dozen cars with this and it was easy to set, flick on and off and go mainly at my own pace on quiet roads or to keep at or below speed limits in unfamiliar towns.

Now, with the Golf, I need to set the distance with one control then the speed with another two ( one for round speed, the other for one mph increments). It’s not intuitive so I hardly use it while with the simple older systems I was a regular user.

The older systems also meant I could easily react to other vehicles. The radar system feels to me that it introduces another step in that I need to react to its “decisions” as well as the traffic around me. Maybe if I used it more I would get used to it.

Wouldn't use it, ever, whatever name it goes by.

Fortunately the truck i drive has simple old school cruise control and i can turn off the gps/terrain supposed 'eco' part of the deal which sees speed dropping before you reach the peak of a hill, which if everyone behind is using radar/adaptive means the whole moving line of commercial traffic slows to the speed of the vehicle that slows the most....i had the misfortune of using another make of truck last week, no way of switching off adaptive cruise so just kept my foot to the floor on the limiter and amused myself watching the on board driving scores get progressively lower because i failed to do as the trauck wished, stuff that.

No different in cars so equipped, someone miles ahead is a hesitant annoying mimser and their driving incompetence reflects in a wave back as far as the traffic lasts, eventually they'll come up behind a road hog and 500 cars behind will all mirror whatever the rolling roadblock is doing, all mindlessly leaving the vehicle to control their lives.

Now this is all vvery well if all you consider yourself to be is a passenger in this controlled box of electronics who just happens to be sitting behind the steering wheel...oh and they're insistent on nudging that for you as well...but do you really only want to be vegetating behind the wheel while the car increasingly does everything for you, might as well catch the bus or train.

Anyway the point is this is a motoring forum, why are you lot not questioning these things more or just simply turning them off and learning to drive again, you are supposed to be drivers with presumably an interest in actual motoring, if not why are you here?? what is happening is chipping away at all that it means to be a motorist, for goodness sake wake up, will there ever be a final straw that breaks your apathy, there are those in power (western politicians apparatchiks and otherwise) out to take your own private transport from you, going along with their every whim only encourages them.

I've got it but I've never used it, I do however use the speed limiter function.

Why do you think people want you to stop you from driving? And as it is the car manufacturers coming out with all the technology are you saying that the government is helping them to push out the tech so the government can then stop you from being able to drive? Why would the manufacturers want that?

Two questions - what does it do on an empty road - try to catch something up ? And can one adjust the following distance ?

On an empty road it holds the speed to whatever you have chosen (eg 60 mph) and doesn't exceed this, but slows if it detects an obstacle in the road in front.

On my Honda CR-V I have three options for the gap from the vehicle I am following (I always choose the default - largest - setting)

I like the speed limiter on mine as it reacts to the road signs, the car I’m interested in however, only alerts that you have exceeded the limit, now before everyone starts posting that you shouldn’t rely on these systems, my answer is, I don’t, I use them as a guide, a back up so to speak, as for adaptive cruise, it makes for a more relaxing drive, as long as you are not completely relying on it, and are paying attention to what’s going on around you on the road, I’m all for the gadgetry in new cars, ( dare not mention that I have an automatic tailgate)

Hmm. These days many speed-limit signs (and plenty of others) are turning green with algae or are partly hidden by overgrowth, so I don't know how reliable that is. There have also been cases of loonies converting a 30 sign into 80 (for example) which could be interesting.

Yes, that’s something I should have added, it’s not infallible, in fact it sometimes doesn’t work at all for a few miles, not seeing a road sign, or seeing a 20 sign in a side road and adjusting to that, but as I said, it’s an aid, and not to take responsibility from the driver.

Being almost permanently on cruise does lead to one of my pet hates - drivers who don’t hold a constant speed.
I set cruise on a motorway at 72mph, a GPS 70. I catch a car doing 65 in the centre lane, or lane 3 of a 4 lane stretch.
I indicate, if required, to pull into an overtaking lane and, lo and behold, the car previously doing 65 is now accelerating. I’ve never been sure whether it’s a conscious or subconscious thing. Possibly a general lack of awareness.
I’ve now got two options to avoid doing an impression of an LGV passing another heavy - add a few more clicks to the speed via the cruise button (pedals are so 20th century) or slow down, causing confusion to whoever’s behind me.
If only people would use cruise when it’s available, or have some awareness of speed, we’d all have a less stressful drive.

To take this to the next level....I have noticed a growing trend among the middle lane hoggers. They put their adaptive cruise on and sit there speeding up or slowing down depending on who is in front of them. I have old-fashioned cruise, so set it to seventy and change lanes accordingly. The net result of this is (excluding those not on cruise), half of us are maintaining speed and changing lanes and half are maintaining lane and changing speed. This is not a very enjoyable experience.

We had one like that today. It must have followed us for 25 miles. We were switching lanes and trying to maintain 70 mph, they were stuck in the middle lane doing whatever speed the car in front was doing. When we pulled over and started to slow for our exit they accelerated hard past us then slowed down for the car in front. Why they couldn't have overtaken like we did I do not know.
