I have a 2020 Forester and I've come to describing it as "I no-longer drive on the highway, I manage the car." Sometimes I'll get nervous and take over. But even in stop-and-go traffic, it has behaved perfectly. My only complaint is that there's an over-eager PID loop with lane keeping. If I want to pass a transport truck and want to kind of edge to the left of my lane when doing so, it will keep trying to compensate, which I can feel in the wheel, so I compensate for as well. And if I let go of the wheel and let it win, it suddenly flings me towards the right side of the lane. I suspect this is because it isn't programmed to think that I'm making adjustments, it probably just thinks there's some weirdness in the vehicle dynamics/road characteristics that requires extra compensation.

My volvo also has a "not perfectly tuned" PID loop. With "autopilot" engaged it keeps weaving constantly left and right inside the lane im in. Have gotten used to keeping a firm-ish pressure on the steering wheel at all times to compensate. But drivers behind me must have thought me drunk before i got the hang of it.

  This is lane keep assist not lane centering and dangerous to use as a lane centering feature as it’s not designed to do that hence the ping ponging behavior

    Lane keep assist is always enabled, this "copilot" or whatever it's called is an extra feature i can manually enable over the default lane assist. And it will steer and follow the road quite well in most conditions. But sometimes it starts the ping pong behaviour. Should also be noted that i never take my hands of the wheel. And the volvo is quite fast at beeping at me if it detects that i dont hang onto the wheel.

Have a EX90 I got on a really great deal, we drove it cross-country and it was mind-blowing how little I had to do. If it didn't make you touch the wheel / pay attention we could have basically done the entire trip without incident minus off-ramps. But there was one thing that was quite bad, similar to yours. While passing a semi I pulled it to the left side and it actually yanked us right so hard and then over-corrected once again. Super scary moment, the only issue of the whole trip, but basically never passed with it on again.

  How you like that car? I test drove an early model that was really a pre-release dealer demo. It was a great ride but I also didnt get to do a whole lot with the sales guy next to me and a tight deadline to get back home.

    Made me want to invest in Volvo. They fixed most of the software issues, what's left is a shockingly nice experience. Touch screen can be a bit annoying is all, but Google integration and design of the UX in the touchscreen is really good.

I have a 2023 Crosstrek, my wife has a '21 Ascent. I have the same habit you do - edging away from large trucks slightly - and both of them do the same thing you described to me. It's essentially that Subaru's lane system actually has two levels: it has lane keeping where it's just trying to keep you inside the lines, and then on top of that it also has lane centering which is pretty much what it says. Just a note for you or anyone reading who has a recent Subaru and doesn't know already: if you find the centering really bothersome, you should be able to be able to go into the settings on the instrument cluster display (up/down arrows at the lower left behind the wheel, toggle it until you get to the "hold for settings" option), find the Eyesight settings, and turn off lane centering. It will still try to keep you inside the lane markers but won't try to park you right in the center of the lane. In that mode, it's more like the Honda Sensing system I had on my 2016 Civic. I go back and forth a bit on it but mostly keep it in lane centering mode now - I've gotten used to how it positions the car in the lane, and it lets me focus more on what's going on around me than micromanaging lane position and such.

  > It's essentially that Subaru's lane system actually has two levels: it has lane keeping where it's just trying to keep you inside the lines, and then on top of that it also has lane centering which is pretty much what it says. Same with Hyundai except they call them "Lane Keeping Assist" (LKA) and "Lane Following Assist" (LFA) and I have trouble remembering which one centers you and which one just keeps you from leaving the lane. To me just based on the names I'd have expected keeping to be the one that actively positions you (it keeps you centered) and following to the one that just reacts when you are going to depart the lane (it keeps you following the lane). Mostly now I just remember that the one that comes on automatically any time I'm going 40+ mph is the reactive one, and the one that I have to explicitly turn on is the centering one (although both come on automatically on certain highways based on data from the navigation system).

    idk whether subaru is exact the same as hyundai but i basically turned lane centering off on my hyundai. when possible i only use radar cruise control, and lane follow. if i want to overtake, turn on my signal and it'll automatically safely increase speed to set cc speed and let the lane follow off. it's pretty seamless. lane centering is a bit too annoying for me, i need to keep my hands on the wheels anyway.

Don’t most of these systems release the lane-keeping when you turn on the turn signal? Does yours not, or do you not signal until you are trying to exit the lane? (Genuinely asking.)

  I’m not trying to exit the lane. I’m hugging the left side of my lane as I drive past a transport truck.

But even in stop-and-go traffic, it has behaved perfectly. I drive an old beater from 2001, but... I really don't think I understand why people want these in-between not-quite-autopilot features? To me it's like, it would be one thing if you could completely turn your brain off, or look at your phone, or rest. But since you can't, it seems like this stuff makes it more difficult to pay the appropriate amount of attention? For me, if I'm already driving somewhere, and have to pay enough attention to know if an emergency is about to happen, I might as well just do the driving.

  I prefer to steer, but radar cruise control takes a lot of the frustration out of minor speed fluctuations in front of me on the highway. I don’t feel as much need to pass all the time.

  The cognitive load is greatly reduced when using these features. Honestly, adaptive cruise control in the city is a godsend. Not having to deal with watching speed . start and stop traffic is also automated for me. Driving on a highway is also great .. You can drive much further without needing a break.

  As a technologist, I like lane-keep assist because it feels fundamentally more right that my car by default follows the road than keeps going with the turn radius I had previously input. Cruise control with minimum distance helps me keep a sound distance even as other cars keep packing up and reducing distances on a busy highway. My previous car (Mercedes) was great at detecting if a new car coming in front of me was accelerating, if so it didn't adjust the distance as aggressively. Much better behavior than my current Kia. Auto-break features are sweet as they react really fast. If that can avoid deploying an airbag in my face, I'm all for it. I agree it's a lot like managing, with six buttons just to do the above, but from a bottom-up approach, each feature has value in its own right. > For me, if I'm already driving somewhere, and have to pay enough attention to know if an emergency is about to happen, I might as well just do the driving. Where do you draw the line? Would you prefer not having a steering and brake servo? Would you prefer sticking out your arms instead of having flashing lights? Would you prefer feeling every bump in the road to having suspension? To me these systems just feel like natural evolution of the car concept, something that's been going on for 120 years. What Tesla failed at was putting their heads in the clouds and hoping something awesome would eventually pop out the other end. While the established car makers did incremental improvements.
