I am currently in the middle of a 500 Mile Road Trip and I am extremely displeased with the autopilot update. It seems no matter how I squeeze, push or do whatever to the steering wheel there is no simple way 2 make the hold steering wheel notification go away. My hands are feeling very fatigued my focus on the road is about as bad as it can be since these notifications come up every 12 seconds. I personally would not go through this again on a future road trip. Not using autopilot in my opinion would be way safer based on what this is causing me to do. I know they are trying to make people be more attentive but I think this was a big swing-and-miss and is anything but relaxing to drive. Version I'm on is 2018.21.9. . If you are planning a road trip in your car and like using autopilot I would not get the software update not only cuz it's extremely annoying I believe it is way less safe. Now it did mention something about autopilot being better when merging on a highway but that's something that is a very rare situation verses taking your focus off the road every 12 seconds to give the steering wheel a personal massage to make it shut up.
Either this is a hoax, there's something wrong with your car, or you're really doing something wrong. See the above posts and the next paragraph regarding the latter.
On mine, the nag is about the same on surface streets and more frequent on the highway. BUT, the sensitivity of the steering wheel to cancel/prevent the nag seems much more sensitive. Prior to the update, I had to put my hand up off of my leg a few inches on the steering wheel so that the weight of my arm would put enough torque on the wheel for it to sense me. Now, even on a straight road, I can rest my arm on my leg and simply hold the wheel with my left hand at about the 7:00 position. The resistance of my hand on the tiny corrections that AP uses to stay in the lane is enough. It takes significantly more effort to keep my head upright to watch the road than to do this so there's absolutely no way it causes any fatigue. Though I am starting to get arthritis in my thumbs so maybe on a multi-day road trip I'd get sore enough to need a couple ibuprofin.
The nag is super lame. Blame the dumbasses who completely quit watching the road and killed themselves, ran into fire engines, etc. and then they or the media blamed AP/Tesla.
I'd strongly prefer to have the inside camera verify that I'm watching the road and let me take my hands off of the wheel... at the very least on the highway. As long as I'm paying attention and preemptively take over when I see something coming that AP can't handle, I'm perfectly safe. Everything has to be engineered for the dumbest person punishing the rest of us. I'm not seriously this cold hearted and it would be a PR disaster for Tesla... but there's a part of me that wishes they would just get rid of the nag completely and let natural selection take its course.
