Lane Keep Assist and Lane Centering

My experience is quite different. I am grateful of these systems. In our family with very experienced drivers, the emergency warnings and break has reacted far faster when another driver does unexpected stupid things: jump into a lane when there is not enough clearance for their big truck, slam on the breaks in the middle of the highway because they just missed their exit, jump in and out of an HOV line due to slow traffic into 70MPH traffic, distracted by their phone and come barreling straight on, etc. Even pedestrian that jump into a street with moving traffic. The park assist, cross traffic warning, and backup cameras also have prevented minor and big accidents when backing out of a parking that has been blinded by vans or big trucks park next to the car. Those safety systems have save us from several accidents. Not counting, the many times I have seen the lane keep assist help distracted drivers realize they are drifting out of their lane on cars driving in lanes next to my car.
Fortunately, you can turn off these features if you do not like them, but they do not really add much to the cost of a car. The cameras, ultrasonic sensors, radars, and microprocessors on these systems are under $200. The major cost is the calibration, extra installation, and alignment. Car manufacturers just charge a lot for their perceived value. Moreover, many customers have seen their value and embraced them, particularly with so much distracted driving. So it is a new way for car manufacturers to sell new cars, or provide a good reason for someone to upgrade their vehicle. Granted, these systems are not perfect, but they are getting better with improvements in processing power, sensors, and cameras. In all, these safety systems add an extra layer of protection, like wearing a seat belt. I will not buy a car in the future that does not have these safety systems.
One thing I would wish, is that all these cameras and sensors were also used as dashcam and security systems when the car is parked.

I agree, but also as a dashcam replacement, where it would be integrated with the screen and be a total replacement for dashcams.

I would also suggest that there safety features are making us all worse drivers. The more the car does, the less the driver pays attention as even evidenced by automatic transmissions vs manual transmissions. My view is that drivers assistance systems will be short lived and we will quickly go to full automation as doing half the drivers job doesn’t allow him to better focus on driving so much as allow him to stare at his cell phone that much more.

If I relied on my lka to prevent me from veering off into oncoming traffic, I probably would t be here making this post.

It's also scary how stupid people believe the safety system can take over. Just google all the Tesla car crashes where the driver was letting the car drive itself without supervision... Even I get confused with some road markings that do not make sense. Can't imagine how a few cameras and a simple $100 microprocessor could make sense on those roads.

Yes, isn't out ridiculous how much they charge. Just like navigation systems: Add a $10 DVD reader with a $25 microprocessor system, a $5 GPS, and a $30 VGA LCD panel and charge $2k. You can buy a tablet with GPS, microphones, speakers, better touch screen, and many other features for less than $300.

Just wait for it. The time when autonomous cars and AI are more superior than human drivers will come soon.
Think back how technology has been evolving in the last 30 years, it will only get better from here.
“Just google all the Tesla car crashes where the driver was letting the car drive itself without supervision...” So have you researched how many people die a year when the human drivers fall asleep or gets distracted?
The fact that some stupid people don’t monitor their tesla does not mean autonomous technology is worse than human drivers.

“how a few cameras and a simple $100 microprocessor could make sense on those roads.” Computers react much faster than human drivers. However, the state of autonomous technology as of now still requires human attention because we are in the middle of building the technology. So I don’t think you should assume a few cameras and a simple $100 microprocessor cannot make sense of the roads. It totally can sooner than later.

No question it’s coming fast. It is and will be more to do with societal and legal hurtles that holds it up than from the technology its self. Pretty bleak future for the car enthusiast so I’ll do my best to avoid as many advanced driver assistance systems during my last bastion of freedom before the machines take over.
It's just some areas will need better road design for these systems to navigate. For example, this intersection always confuses me:
Crazy intersection on a Texas highway bridge

Long-ish demo video of the systems in the RX, let me know if there's anything I missed!

I don't believe in some of these safety aids that car manufactures are adding these days. I agree with gadgetman1 point that they can be unreliable. It also makes drivers depend on technology to drive and create bad driving habits.
Dang, you must pass a driver's test for license, and then go buy a car to correct the questions you got wrong. I think if you can’t drive good enough to stay between the road lines. You may need a little more practice and not a car to help you or tell you when you're too tired to drive. So, will we still need a driver's license to operate an autonomous vehicle?

LTA Not Very Good
My lane keeping assist is not working well. The car goes from side to side and over the line before corrective steering kicks in. Not good enough. I have seen YT videos of the set up and in one of those the center screen has an LTA button you can select and you can choose centering. My 450H luxury is not showing that LTA button. When I turn LTA on from the steering wheel it shows it is on but does not center. Any suggestions? It is a 2020 with every option I know of.

My '17 will pull to the right until it crosses the line and lane departure warning kicks in, this feature simply does not work. It feels like it's not calibrated properly or something.
Would be nice if this worked for the long drives on cruise control but you have to fight the steering wheel or it will run into the car if there's one on the right side.
