Mind boggling to me that a non-ping pongy lane keeping is not standard in cars. Is it standard in luxury cars? Seems like an obvious thing to add/upsell.

Non ping-ponging lane following assist is already available in many cars including KIA and Hyundai models. They're very conservative and disengage very easily. I think it's by design to minimise their legal accountability

  Also Honda. In my Accord 2018 it lane kept but didn’t even play a sound when it lost tracking.

  Not just legal accountability, but actual safety. They are designed so that they do not give the user a false impression of the extent of their capabilities.

  Hyundai actually has two systems, LKA and LFA. LKA just tries to bounce the car back when it detects lane edges, LFA actively keeps the car in the middle of a lane. All Hyundai models in Europe have LKA, some (more expensive) also have LFS.

  I've been incredibly surprised to see that lane assist in my Kia is significantly better than that of most other (legacy non-hi-tech, think nicer hondas and lexus ICE/hybrid) cars I get a chance to drive. I unfortunately don't have radar cruise control on my Kia, though, which would make highway driving even in traffic completely effortless, and this seems to be standard on themore expensive cars. Maybe it's for the better, though, because it does force me to be much more attentive on the road.

    I am addicted to radar cruise + lane assist in my Kia. I use it all the time in traffic.

My 2019 Audi S5 was excellent at this. It would ping pong at most once then auto-correct itself to be perfectly centered in the lane. It did some weird things like if the car in front of you was driving a bit too far to the left/right of a lane, it would copy them. Other than that it was nearly perfect, though. Never had it take an exit by accident, etc. Their tuning on when to accelerate/brake and make it smooth needed a fair bit of work, but I found that switching the drive mode from Dynamic (Sport) to Comfort changed the eagerness of the system and smoothed things out.

OT1H, "lemmings," but OTOH unless the whole line of cars were all on openpilot my life experience has been that the person in front of me by definition has more visibility than I do since their car is not blocking their view as it is mine I am totally talking out of school, because I'm not in that space and my poor BMW chose to do its own thing[1] so it doesn't work with openpilot[2] -- although they have a dedicated #flexray channel[3] so hope springs eternal 1: https://en.wikipedia.org/wiki/FlexRay https://en.wikipedia.org/wiki/FlexRay 2: https://github.com/commaai/openpilot/issues/44#issuecomment-1007002547 https://github.com/commaai/openpilot/issues/44#issuecomment-... 3: https://discord.com/channels/469524606043160576/533838492443082774 https://discord.com/channels/469524606043160576/533838492443...

I don't want my car driving off to the side of the lane just because the car in front isn't centred. It should assume the right thing to do is to follow the rules, and hand off to me in cases that are more complicated.
