Lane Assist explanation

[Smig]

Is lane assist supposed to keep the vehicle in the middle of the lane or does it only activate if you step on the line to bring you back in? I've test driven a Peugeot that was doing a pretty good job keeping the vehicle centered and I was hoping this would be the same but I suspect it's the later. It does correct the path if I go too far off course but it doesn't seem to turn for you in normal conditions.

It's just that sometimes, especially in some narrow winding roads it seems to activate more frequently and it feels really nice to relax the arms and let it turn for me, but it's really rare.

Depends if you have adaptive lane guidance or travel assist enabled. If you do, it'll stay central

If not, you'll bounce between the lines.

I probably don't have those. I have lane assist and ACC. Sometimes it feels like it's keeping the car centralized but it activates so rarely and randomly that it's probably just a side effect of pulling me inside the lines in some roads.

Adaptive lane guidance is easy to enable, as is travel assist if you replace the steering wheel

Interesting comment, as I have just moved from a 2022 Formentor to a 2025 Terramar.

The Formentor behaved just as explained, keeping the car mid-lane, and when required compensating for curves.

The Terramar does not have the same feedback, so although there's a steering wheel wobble/feedback. Its much less effective tive at maintaining the mid-lane position. And in a low speed test, it didn't correctly maintain the curve on a slow corner.

I wonder if any of these settings can be tweaked? As I found this summary, "Adaptive Lane Guidance in a CUPRA car is a system that helps the driver keep the vehicle within its lane. It uses a camera on the windshield to detect road markings and, if necessary, gently steers the car back into the center of the lane.
This feature is often part of a larger Travel Assist system that also includes Adaptive Cruise Control, allowing for automatic lane changes on the highway. "

Don't confuse travel assist with lane assist, they are very different things.

Unless you have the specific button for travel assist on your wheel then you do not have travel assist on your car, lane assist is only to stop you leaving your lane if you are a terrible driver and aren't paying any attention.

I have a 11/2024 Seat Leon ST e-hybrid FR with all those systems. After some scares the first thing I do when I start the car is disabling them. Too intrusive and frankly badly engineered. As examples of the scares I can cite sudden brakings/swervings when the radars detect non existent obstacles (seem to occur more often when there are metallic parts like traffic sign posts around), strong pulls on the driving wheel when the lane assist thinks strong shadows on the lane are lane markings (happened twice with shadows cast by the cables of a suspension bridge in my home town, during very bright sunlight periods). Too bad some of these systems cannot be deactivated permanently. It is a sad reality that car manufacturers insist on pushing costly half-cooked solutions into new cars for marketing purposes. (Observation: I am an engineer very open to new solutions and technological aids, but not at any price.)
