I have a VW Golf and it has what it calls "adaptive cruise control". What makes it different from my older (simple) cruise control is that it will slow down and speed up again as necessary without my intervention. For example, if I set the speed to 70 mph and it gets close to a car ahead that is only going 65 mph, it will slow down and maintain what the software believes is a safe distance. Similarly, if a car in an adjacent lane changes lanes in front of me, it will slow down if necessary. I do use it, but less than I did the old system: I just do not find it relaxing because I cannot really grasp intuitively when I need to override it. On standard cruise control, it was obvious to me when I needed to take over. Therefore I am more rather than less vigilant than I was with the old system. I don't want to be too hard on the Golf: it has other safety features I really like, such as lane assist and automatic breaking. But I am not a fan of the adaptive control, and I think the article help me understand why: its a level 2 problem!

I would never want that though. It should change lanes and pass.
- code_runner 4y ago
  It can if they want it to. It’s a car.
- MBCook 4y ago
  It’s very useful on long drives since you don’t have to constantly adjust your speed by little bits (manually or adjusting the cruise control setting). Takes a moment to moment mental load off so you can focus on the other cars around you better. If the cars ahead of me are slowing down significantly I disengage and go manual until I have a better idea what’s going on. My car can supposedly stop completely that way. I’ve never tried that, as it gets very slow (relative to highway) it’s willing to get way closer to the vehicle in front me than I am. I trust it (in theory). But it’s not worth testing.

    I wonder why this is preferable to just taking the train for longer trips? Wouldn't it be nicer to sit back and let someone else do all the driving for however many hundred of you are all going to the same place anyway? Once you get past the long part of the trip you could always rent a car if it's rural or whatever.
    - Rebelgecko 4y ago
      Kind of derailing things, but train usefulness varies on area. At least where I live, train journeys are usually more expensive and significantly slower than a comparable flight (maybe similar speed to driving but still more expensive). And for a lot rural areas it's not a viable option
    - MBCook 4y ago
      ACC is nice on freeways around town if traffic isn’t heavy (I like more control when it is). Long distances is where it really shines. Really the train isn’t viable in most of the US. And then you have no car at the end, probably in a city with bad public transit unless you want to take taxis/Ubers or have friends/family drive you around. So for long hauls, it tends to be a car or a plane. And that decision is heavily influenced by distance.
    - eric_the_read 4y ago
      The only train I could find that goes anywhere near my mother's house would take approximately 12 hours, with a 5 hour layover in a small town with ~nothing to do. I can drive it in maybe 1.5 hours. That's why.
      - komali2 4y ago
        Is this considered an acceptable situation to you and your community? What does your government representative say when you demand better public transit solutions?
    - toast0 4y ago
      The train would be nice if it was a reasonable alternative, but in the US outside of very specific trips, it's usually at least twice the travel time as a car, door to door, with two drivers and maybe 10-12 hours of daily driving. And then you've still got to manage ground transportation from wherever the train station is to wherever you want to go. It's great if you're a container though.

Don’t you just tap the brake to disengage adaptive cruise?
- thaumasiotes 4y ago
  The problem isn't that disengaging the system is difficult. The problem is that deciding whether to disengage is difficult. If you're catching up to a slower car, maybe you should disengage the cruise control. Or maybe you shouldn't. You can't tell. This means that cruise control goes from being something that relieves stress on you to something that causes additional stress.
  - netsharc 4y ago
    Seems like the car should have a UI that says something like "Car ahead is 15km/h slower, I will brake to maintain 50 meters distance between us, current distance: 70 meters, approach speed: 4m/s, will start braking in 3 seconds.", so the driver knows that the computer is aware of what's going on. Use some pretty graphs/animations to make it easier to understand.
    - MBCook 4y ago
      I’ve had two cars with the feature. Both have a very simple there/not their car silhouette to let you know if it detects the car in front of you. Just below that they also have some sort of colored to tell you how close the car is (good, clothes, to close). Last is a silhouette of your car. All three in a simple stack. It’s an excellent design, perfectly glanceable. I did rent a car once that showed you how many feet away the car in front of you was. It was kind of interesting but I found it completely useless. Realistically when the car in front of you starts getting close enough that the indicator changes, the car is already slowly slowing down. If it turns red, your car is slowing down faster. You really don’t need any of the numbers, and they would likely take longer for a person to process than the simple visual imagery does. I haven’t had an issue of not understanding what the car is/is going to do. The only real prop I’ve experienced is some cars are willing to accelerate/decelerate much faster than I want them to, largely for comfort reasons.

I do love the ACC on my car. One of the worst parts of road trips is following cars you don't want to or can't pass. The ACC totally solves it. I don't see how you were really able to use cruise to follow another car at all before? Even 1mph too slow is not great and if the car in front isn't using any cruise control at all it could be 5mph too slow and then 5mph too fast.
- Johnny555 4y ago
  In my car without ACC, I just hit the up/down buttons to adjust the speed for the car in front. Not a big deal when there's a small speed difference, but certainly not as convenient as ACC.
  - mypalmike 4y ago
    Some percentage of people (probably well into double digits) don't know about the up and down speed adjustment buttons.
    - DangitBobby 4y ago
      I do. They aren't responsive enough and the people in front of me aren't maintaining a consistent speed, so I just switch back to the pedal unless I'm pretty much by myself. I rented a car with adaptive cruise control and really loved it.
      - Johnny555 4y ago
        In my case, the car without ACC is an RV and since driving it is like trying to push a small house through the air, it responds pretty quickly to speed reductions. Plus I tend to keep a pretty long distance from the car in front of me, so I have more time to respond. I like to pick a truck to pace behind since a lot of people don't want to get stuck behind a truck so they don't pass me then pull in behind the truck, even with 5 or 10 seconds of following distance. Another advantage of pacing a truck is that they usually keep a pretty steady speed unless they are going up a hill, but then on the hill I can usually find a truck that's light enough to keep a pretty steady speed uphill.
marktolson 4y ago
My friend was using adaptive cruise control while towing a caravan. A car merged in front of him, his car applied heavy braking to maintain the desired distance (not necessarily to avoid a crash) but didn't compensate for the weight of the caravan. Almost lost traction, lead to heavy swerving. He's vowed to never use it again.
- Johnny555 4y ago
  Doesn't his car have ABS? Even under heavy braking, the car's wheels shouldn't lock up and lead to swerving. Did the trailer have its own brakes?
  - whiddershins 4y ago
    I believe you are thinking of skidding, not swerving.
    - Johnny555 4y ago
      I don't see how the trailer can force a car to swerve without any loss of traction through skidding.
  - Rebelgecko 4y ago
    Does ABS help if the car is braking faster than the trailer?
  - btilly 4y ago
    As everyone is pointing out to you, ABS solves the problem of your car's wheels skidding, leading to loss of control. It doesn't help with the trailer that you're towing failing to stop as fast as you do, trying to run into you, and trying to turn to the side when it can't. The solution to the latter problem is to be aware that you have the trailer, and to not brake faster than it can handle. The fact that the trailer makes it harder for you to avoid an accident is exactly why many jurisdictions put extra restrictions on cars towing trailers (for example in CA they aren't supposed to go over 55 mph - even on the freeway).
zoklet-enjoyer 4y ago
I have adaptive cruise control on my Subaru Impreza and I love it. I use it on trips around town and on long road trips and it's great. I will never buy another car that doesn't have this feature.
eyelidlessness 4y ago
I rented a RAV4 recently for not one but two cross-US trips (Seattle <-> VA). Its adaptive cruise control (like its lane assist) felt mostly familiar from previous rentals. It takes a lot of getting used to, if you’re from a time when cars just mechanically do what you tell them (failure modes aside). That said, I have the almost opposite take! The adaptive CC wasn’t perfect, but it had a perfect failure mode all but one time: it just stopped working at all when its sensors got fudged in any way. The one exception was a near pileup when drivers ahead of me came to a sudden stop in the middle of an urban ramp soup that’s always high risk. Even then it did the right thing: it screamed (beeped) at me to brake, because I needed to control that and it had no safe way of doing it for me. I’m similarly more vigilant with assisted CC, but I’m more inclined to use it because it makes me more vigilant. I almost never used a plain CC without it because it’s too easy to get lazy at the wheel and make mistakes. Constantly checking on the known-limited computer kept me alert but let me rest my legs for ~10k miles over a month and a half. And it saved my ass on a sudden ice patch in Nevada, which was the other time it didn’t work exactly as expected. I don’t drive with a computer in control, I only delegate to it for menial tasks like predictable speed adjustment. But I’m grateful I had the computer to help me regain traction coming around an icy bend when the alternative was me and my pup and everything we had in tow were going to roll off a mountainside.
- MBCook 4y ago
  I also like it because without having to stay so heavily focused on my speed I can spend more time on situational awareness of the other cars around me than I would with traditional CC or no CC.
  - randerson 4y ago
    I use ACC even in short bursts when merging onto the highway or changing lanes. Turn on ACC, then look over shoulder to check blind spot without worrying about the car in front slamming on brakes while my head is turned.

int_19h 4y ago
I might be missing something but wouldn't it be perfectly fine to override it in the exact same cases you'd override regular cruise control? Sure, many of those might not be necessary; but if you do it, the experience shouldn't be any different from what you're used to, no?
- JKCalhoun 4y ago
  I think their point being that, being adaptive, it lulls you into a sense that "oh, the system will see the car ahead slowing down and will slow down my own car for me." Older "dumb" cruise control you had to be ready for the brake at all times — there was no need to second guess the system.
brewdad 4y ago
I have to do the drive from Portland to Seattle about once a month. ACC makes the drive so much more enjoyable. I can pretty much zone out until it is time to pass someone. Then, depending on speed differences, I move over and pass without intervention or I press the throttle a bit to pass more quickly. When I get to the inevitable slowdowns, my car just slows without me having to think much about it unless it’s a sudden one. I also have a Golf with standard cruise and I can’t stand using it since most drivers around me can’t maintain a constant speed, so I am always adjusting it or canceling it.
- iainmerrick 4y ago
  I can pretty much zone out That seems bad!
- progman32 4y ago
  I've caught myself doing the same on occasion. I try not to do it anymore. If I may, I'd suggest to replace "zoning out" with "applying my freed mental bandwidth to monitor things that I would otherwise not have been able to pay attention to otherwise". IMO, driving aids should be used as emergency backstops and possibly a method of optimizing available attention. They are best avoided as an excuse to reduce overall attentiveness. For example, when ACC is on I can more reliably look a little farther ahead in traffic to preemptively react to developing risks, because I'm not micromanaging the throttle.
originalvichy 4y ago
In my driving style the ACC helps me by letting me focus on only braking. Without ACC taking care of the throttle, I would have to micromanage my speed to keep it above an acceptable limit so I won’t get annoyed followers. With ACC I can decrease the amount of foot shuffling and just rest my foot next to the brake pedal in case something happens up front. My car model comes with emergency braking that can be toggled off but it worked perfectly one time a driver slowed down unexpectedly (alerted me first, then braked).
robbiep 4y ago
My Mazda has adaptive cruise control - it has absolutely revolutionised my highway driving. It is intuitive because the heads up display gives you a distance to the vehicle in front; and you can set the distance you want to maintain. It tracks your progress/distance so you can see when it will slow/maintain and it behaves gracefully if someone cuts in
- oblio 4y ago
  I don't know how the Mazda one works, but for Volvo you actually get 1-pedal driving if you want. Set the speed a bit lower than your expected speed (for example in crowded areas), then accelerate as you wish. Once you take your foot off the gas, the car is set at a lower speed, so it brakes for you if needed. Ta-da! 1 pedal driving :-)
  - robbiep 4y ago
    That’s interesting - haven’t seen that
jaclaz 4y ago
I once rented one of those Golf at the airport, didn't like specifically the Golf ACC (possibly it could be somehow tuned/set differently) because - at least in my case - while driving on the leftmost lane it could "see" a car merging on the leftmost lane (to overtake someone going slower) at a too big a distance, immediately slowing down even if it was unneeded, really plenty of space before my car, then re-accelerating to the set speed as soon as the car in front returned to the right lane. In slightly heavy traffic conditions on the highway it was unpleasant/confusing.
lajosbacs 4y ago
I have an older BMW with ACC and had a Tesla Model 3 as well. The ACC on the BMW rocks, it reacts quicker than I do when a car slows in front of me, but never vigorously breaks. Phantom breaking is unheard of. It only needs attention when the car in front leaves the highway and starts slowing down. But the manual specifically addresses this. On the other hand, I found the dumbest 'cruise control' mode on T3 downright dangerous, you always had to have foot on the gas to be ready to override it. They just took something that was solved a long time ago and made it worse, I really do not get it.
