    Honestly, I like the ACC and lane centering on the Tundra. The lane centering is great for my long commute and road trips.

    My wife's Chevy has the same lane keep/lane centering features and they are not nearly as well implemented. On the Chevy, if the lanes shift left or right through an intersection, then the car will jerk aggressively back to where it thinks the lane should be. It doesn't realize the lane is "sliding" over a few feet on the other side of the intersection. I've never experienced that with my Tundra.

    Any additional thoughts at this time? Was looking at Consumer Reports lately and they don’t speak favorably of the Toyota features versus say a F-150. Did sensitivity adjustments make it better?

    For everyone else that wasn’t impressed with LCA, did you look at your settings and make adjustments?

    It works fine, but not on twisty roads. Any turn over 30* degrees expect to help it by yourself

    Exactly, it works OK on straight flat roads. On curves, especially when it is also hilly, not so much. And it does some odd things that depend on how a particular state marks their roads, like around exit ramps. Here in MD, at least, when I approach an exit ramp where that right side lane line begins to curve off the Tundra starts to follow that a bit to the right before it realizes what is happening and comes back. I should say SOMETIMES realizes and comes back. It's like it isn't looking far enough down the road to "understand" the big picture. In some other states with somewhat different marking it works a little better.

    I liken this system to those old extremely basic TMPS systems, like on my old Tacoma, that didn't even tell you which tire. IOW Toyota seems to have done the bare minimum with the lane centering assist. They really need to add some AI for this to work properly. Frankly, I am disappointed and this is one thing that may get me to trade in a few years to get something that has better technology.

    Edit: as an aside... On a business trip back in ~2018 I had a Camry rental that had the first gen lane keeping assist. It didn't have lane centering, just the LKA part. I was intrigued and gave it a thorough test mostly on wide and well marked 2-lane highways. I honestly don't believe the Tundra does any better than that first gen version. The Tundra will stay a little closer to the center of the lane if lane centering is enabled. But it doesn't really do any better than the Camry in resisting departure in curves. IMO.

    I thought Lane Assist was awesome when I bought the vehicle but after 3x trying it out, I didn't really trust it and never used it again. It works fine but there's not a situation where I'll be driving and have both hands off the wheel trusting a computer. I've been driving for almost 30 years so steering actively isn't a problem for me, it's how I've always driven.

    The Adaptive Cruise Control I do really enjoy and use it quite often.

    Gonna answer these in order
    1. Yes I love it, I havent bought a new car without adaptive cruise in a few years.
    2. Yep, have it on all the time. It rarely bings though.
    3. I only use lane centering when Im using adaptive cruise
    4. Only on long drives
    5. Depends on how twisty. gently curving highway? Yes. twisty road up a mountain? Nope.
    6. the only cars I have to compare to are 21 Bronco and 21 Lexus UX. Tundras is better than both of them.

    I drove from Dallas to Houston over the weekend and had the adaptive cruise set to 80mph all the way there and back. Worked perfectly. Just one hand on the wheel with some light pressure and it doesn't complain.

    The tech is far from perfect - but it is significantly better than prior years and many other vehicles I've had or driven many miles on.

    1. What's your opinion about it? Ok or terrible?
    I really like all the features. I use them at different times for varying reasons. Overall I rate them highly.

    2. Do you use Lance keep assist? (one that bumps you into the lane if you go over the lane)
    Yes - it takes a bit to get used to, however, it does the job (even when the lane markers are partially snow covered here in MN). It works significantly better then the lane assist in a 2020 Honda Pilot, 2019 Nissan Titan or 2016 Avalon

    3. Do you use Lane Centering? (one that keeps your truck in center of the lane)
    Yes - I use this one quite a bit. I never realized how much I veer over the shoulder marker, but this keeps me honest. Works significantly better than my 2022 Avalon does - guessing the higher angle of the cameras from the windshield has something to do with that.

    3.1 How about adaptive cruise control?
    Sometimes - if there is a lot of traffic and I'm changing lanes often then I shut it off and just use cruise. However - it works very well when there are fewer cars and less lane switching going on. This one seems to work much better than prior years from Toyota too. I had it in a 2006 Avalon and anytime it rained it wouldn't work.

    4. Do you use Lane Centering on twisty roads? How twisty?
    I've used it on all kinds of roads. It reacts fine - but don't rely on it for autopilot - it will help, but can react a bit slower if going back and forth constantly

    For what I paid for this truck it should MAKE me coffee instead of teasing me. LOL! Aside from that my adaptive cruise is a bit abrupt during commute time, seems to be either on the gas or on the brakes and when someone in front of me exits the highway my truck is still slowing down while the car is clearly half way down the exit ramp, then it hits the after-burners to get back to the set speed. Other than commute time is seems fine.

    The truck seems to wander a lot with the lane features turned on but the roads here are crap.

    I also saw that Toyota released Safety Sense 3.0. Doesn’t look like any Tundras are coming off the lines with it yet and from my understanding there is no option for over the air updates to go from 2.5 to 3.0. Anyone know more on that?

    That's because lane centering only works with adaptive cruise enabled and activated. Basic LKA works in other modes.

    TSS 2.5 and 3.0 use almost the same hardware, its just slight upgrades (camera field of view and resolution). Functionally they're extremely similar, 3.0 is just very slightly better in low or mid light scenarios (rural roads with no street lights). For 99% of Tundra owners, the differences will not be noticeable.

    TSS 3.0 can be updated over the air along with system software, but the updates are so infrequent that its not really a benefit. Most Toyota dealerships will load any new TSS software at your oil change.

    Very helpful. Just to clarify - the Tundras with TSS 2.5 can't be easily upgraded to TSS 3.0 because of the hardware differences, right? A huge let down if so. Even if there aren't frequent updates right now, you'd love the option to get any big updates or more frequent updates OTA as times change. Or were you saying even with TSS 2.5, the dealers can you get you caught up to 3.0 and beyond - you just don't get the luxury of over the air.

    I think the last thing they need are upgrades to this thing, get the bugs worked out with what you have first, then hit it in teh mid cycle update in a few more years.

    just be careful, if you need to last minute lane changes w/o a blinker to say avoid a finger drift, it will try to force you back into your lane. you have to be forceful enough to overcome the resistance, which i found surprisingly strong if you are not prepared for it. not fun hitting a finger drift at night doing about 70 :)

    I seriously doubt it. If it does, it is still being held back in machine kiddygarten.

    I know some systems use some version of linux and I was thinking the lane centering could be better if it had a neural network where Toyota can collect data during service to improve tracking and maybe the steering inputs based on current alignment and what not but it's probably expensive to deploy something like it considering gpu and memory prices lol

    Bruh we just added OTA updates and you think we're using machine learning?


    JK. We're leveraging ML in some parts of Toyota, but I'm not at liberty to discuss them :(

    If in the future Toyota's driver assistance comes close to openpilot I'd be very impressed because their models are well trained I tried their challenge but couldn't come close to their mean squared error against their ground truth labels. What really impressed me is the fact that they were running their program on a Snapdragon chip and with some CAN bus control they are controlling all the inputs which is scary but their tests speak for themselves only thing I would criticize is their throttle control but I guess probably to do with them supporting so many mfgs. But openpilot being opensource and all do you as an engineer think it's possible for a tundra to be controlled by openpilot they tried the newer corollas and had success but I'm sure the corolla has drive by wire systems that can be tapped in by openpilot dunno about the tundra though.

    I really miss openpilot on my Highlander I traded in for the new Tundra. The Comma 2 I was using was superb at lane centering with no markings, and the Comma 3 can do even more apparently (with a certain fork off GitHub):


    The link below shows it has been confirmed not to work with the 2023 Tundra:

    Damn you SecOC:goingcrazy: so pretty much our tundras won't validate the inputs from comma because of the 4 byte authentication code on CAN instead of the 1 byte checksum from older Toyotas and only the ecu ram has the key and it's unique to every vehicle right I wonder if techstream... i doubt it lol

    Lane centering is an impressive technology that can assist drivers while they're on the road. It's surprising that some people don't support it. You can still be in control of the vehicle while the system provides assistance, but it's essential to understand the limits, especially at forks, to ensure safety. A recent incident in my area involved a driver who fell asleep and drifted across a double line, crashing into a car with several passengers.

    Also, other safety features are amazing. If the person who rear ended me a couple of months ago had forward collision avoidance then she might've stopped in time.

    A few days ago I got to test out the lane assist with 30+mph crosswinds, and I was really impressed how well it did it's job. Sure, it was a little jerky, but even with some higher gusts, it adjusted accordingly. And by testing, I mean took my hands off the wheel to see if it would keep it in the lane. Didn't know about this feature until a few weeks after I got my truck, but I'm finding that I use it quite a bit.

    My biggest issue with these systems (and this happens in both the Audi and Tundra) - cars are taking left exits, and it's literally just a lane to the left - and they pull into it, and start slowing down... and the safety systems start hitting the brakes, when they are literally over in their lane, causing the vehicle I'm driving to slow down thinking it is going to hit them. I then take over the car, and either disengage the cruise, or push the gas thru - which feels more unsafe then if the system handled the situation properly. I worry about people behind me, running into me at this point.

    I loved the idea someone earlier posted about having Machine learning and doing OTA updates to all drivers on lessons learned such as this. But, as the Toyota person said - they just got OTA working, and don't expect Machine learning to happen anytime soon if at all. Unfortunately, it's that kind of input from thousands of drivers that would vastly improve these kinds of systems across all manufaturers.

    Honda is worse. when someone is almost done turning right and you want to go around them the car will slow down instead of letting you go even though you’re flooring it and trying to veer to the left.

    Frustrating that all this tech has put me in more dangerous situations than saving me from them. I turn most of that crap off except for ACC, which has worked perfectly for me so far. LKAS only on long straight highway trips.

    This is why I keep mine off. I have had multiple occasions getting on the highway and when the left line disappears as the on ramp merges, it will rip the truck into traffic. In my experience, it has been more dangerous than useful. I also didn't know that the settings were adjustable so I will look into that to possibly fix it.

    Glad I’m not the only one experiencing this! Even going around a turn on the highway, the truck tries to steer me into another lane like a crazy person grabbing the wheel. What the hell are you doing, Tundra?

    I may use it on long trips but that's it. I don't use it on any of our vehicles as they all leave a bit to be desired.
