Are there cars shipping now with lane centering that can only handle perfectly straight roads? In my experience most manufacturers currently offer at least one model & trim that has lane centering & adaptive cruise that is functionally equivalent to basic AP. In some cases, e.g. SuperCruise, it's significantly better.

Yes there are some. Eg: Acura MDX. It uses the mobileye chipset and can barely make a highway turn. The car is good otherwise, but it in no way compares to the Tesla ADAS (I have daily driven both). The Tesla has done several trips to LA and back with >1hr between touches on California i5. my commute on bay area 280 feels far more natural on Autopilot when cars cut me off etc. I think performance depends significantly on what roads people drive.

I have a Toyota Rav 4 2021 with adaptive cruise control and lane assist, it worked ok on highways, especially not having it before. You have to keep nudging the wheel every 30 seconds or so which made it annoying.

I upgraded to a Comma 3 and it's basically is night and day. The car never hunts from side to side and it uses eye tracking so I don't have to touch the wheel. Again if you have to touch a wheel on a ACC system, just drive the car haha.

So you run Comma AI on a RAV4? I assume the Toyota has to have the requisite packages already optioned from the factory so the hardware is there? I'm just curious, because I'm leaning towards picking up a RAV4 Prime for my wife to use as a daily driver. I'm not 100% sure I care too much about the technology as a practical matter (I had a Tesla, I usually just drove it myself; but I like driving). But it might be fun to dork around with and see what they've built.

Yea Rav4 Hybrid 2021. afaik it doesn't work on the Prime, although you can check the car chart on the comma.ai site to be sure. I like playing with the forks every now and then too.

I disagree with this. I use to get RSI type pain from long drives. The constant, small tweaks really took a toll on my hands/wrists/forearms.

When my car's lane centering isn't perfect, it still takes 90% of the force off. It's even more noticeable in windy conditions. Lane centering fights all of the gusts automatically.

Fair enough. I just find the steering wheel nag really really annoying. The future is eye tracking or a combination of eye and wheel nag (maybe every 5 minutes or something)
