> My dad's Toyota has this. The issue is it seems to have a hard time actually centering itself in the lane, so it'll just sway from side to side like a drunk driver if the lane is somewhat narrow.

Newer cars (or other cars) do a better job of this. Mine doesn't do the ping pong - it really does keep it centered.

However, the point is that it should direct you back into the lane and you're supposed to take over. If it's ping ponging, it's because you as the driver are letting it.

> Then there's the collision detection thing. It's basically guaranteed to beep at me whenever I enter my parents' narrow street with cars parked on both sides.

Is this detecting at the corners and not the front? For example, my old 2016 car has collision detection, but it will only detect if something is in front of you head on. With my newer car, it's checking the corners. Still, I get the warning only when parking. And I can turn it off.

> But I'm not convinced these systems are that useful if people get used to ignoring them.

Agreed. I think some manufacturers do a better job than others, though.

The person you're replying to mentioned a Toyota, which I also drive a newer model of. It has two modes: lane assist (which works like you have described) and lane centering (which automatically is enabled when you switch on cruise control). The centering will continuously nudge you towards what it decides is the center of your lane.

It's awful and I've trained myself to automatically long press the button on the steering wheel to disable the entire system every time I get behind the wheel.

    This. It's not just beeping; if it thinks you're moving too close to the edge of the lane, it will steer the car to the other side. The only way for me to prevent doing it is by gripping the steering wheel like crazy. Who the hell drives like that?!

    No, having to fight the car just to stay put is a failure of the tech.

    IIRC, this is a 2022 model, so hopefully the tech has improved since.

Most highway exits in Ontario, Canada and some part of the US have highway exit ramps where the right lane widens into two, one exiting and one continuing. The two lanes are not marked until the buffer before the exit. What you have is essentially one widening lane.

The cruise control in my Hyundai is tied to the lane centering feature and this keeps forcing me onto exit ramps i do not intend to take. One time, it was quite aggressive during rain. The lane keep feature does not handle off-ramps in Ontario well at all.

The problem with these "safety" features is that they do not work reliably and do not handle edge cases well.
