How exactly does it fail? Does it just fail to recognize something coming towards you - or does the distance jump around a lot?

It has moments where it just randomly applies the brakes like it sees something, but it doesn't show an object on the screen. I've experienced it with HW3 and HW4. It'll apply the brakes when it can't see over crests where I would think traffic aware cruise control would just not hit something in front of it. If it can't see over a crest it just slows down. I've never seen adaptive cruise act like this in other cars. I'm starting to get used to where it does it most and just hover over the accelerator pedal in case. I feel I shouldn't have to do this.
Yes, its struggling to capture a clean image. Its probably a fail safe - if it can't define a blob it reverts to slowing down. Would be interesting from a control standpoint if it would eventually stop.
Like I said, in factories if we want fail safe we use dislike sensor technologies. Harder to defeat both if there different.
I agree on adaptive cruise. The adaptive cruise and lane centering assist in my cheap Toyota seems to work pretty well, for what it is.
It was excellent in my VW so I expected the best from Tesla's software. I have been a bit disappointed at times. It sucks because the car is absolutely excellent otherwise.
No worries. As a lifelong Motorcyclist, I'm always very aware of my surroundings.
As a heads up if you do want to use it around town it's not bad there, but when it does hesitate at lights you can use the throttle to force it to move and it will take over when you let off the pedal. It's not perfect, but there are work arounds to fill in for the gaps. The tech is awesome when utilized properly. Enjoy it!
To those mentioning auto wipers and adaptive cruise. My Prologue is the first vehicle I’ve had with these features. Auto wipers is WONDERFUL. Adaptive cruise, well, it’s alright, but occasionally it brakes because of a vehicle in the lane next to me, not the lane I’m in. Then after braking for a moment it’ll figure out it shouldn’t be following that car and it’ll speed back up.
And I turned off auto emergency braking both front and rear. Horribly annoying and unsafe features. I changed it from “Alert and Brake” to “Alert Only” and now I have a permanent dash emoji and a warning every time I turn the car on or shift into reverse. That’s less annoying than the car suddenly standing on the brakes in the middle of the road!!
I’m not sure what sensors the Prologue uses but I think it does have radar for adaptive cruise in addition to the camera.
What I’m trying to say is if Tesla can manage adaptive cruise, automatic emergency braking, auto wipers, and FSD with just cameras, they need to license this tech to other automakers. Because except for auto wipers, other automakers don’t have this down.

The only caveat is that traditionally auto wipers have to have glass with much better quality/clarity than non- auto wipers. Years ago while working for a dealership they had a Fiat 500e that needed a windshield. The glass company asked if It had the automatic wipers. Yes, why? Well the regular windshield was $300. The windshield compatible with the auto wipers was $600. Not sure if this is still an Issue with other makes as Fiat didn't sell alot of 500's and the 500e was only sold in California, Oregon and one other state at a $14k loss per vehicle.
They don’t license it out because it doesn’t work that great. My VW was great in nearly every measure and I’d call the adaptive cruise just about perfect.

Not that easy when it turns to a liability situation, passing blame, etc.
Someone’s kid gets killed by an automous EV. Is that ok because its death rate is similar to all motor vehicle fatalities? No thanks. Sounds like a way for deregulation advocates and profit mongers to play sea lawyer amidst their failures.

And to build on that, auto wipers can also be fooled. And they don’t always run at a rate I like/prefer. But the reality is that any idiot driving in the rain needs to have wipers, and auto wipers erring on the side of excessive, annoying high speed wiping is a default that doesn’t have the potential for any harm.
Big difference from a luxury nice to have that is performing multiple safety critical decisions.
If the death rate is similar to human driven cars, then it's not worth going autonomous. But fatality rate drops by 75% going to autonomous vehicles, you're opposed to that? If the fatality is due to a flaw in the software, then sue the manufacturer. If the flaw is due to a broken sensor and the owner didn't repair it, sue the owner.

But you said to judge against the driver. That’s an open ended argument. What is better? 75%? 50%? Many folks who have had to deal with auto fatalities would probably say just one person would be a win. Yet then you go down a slippery slope of nanny requirements.
I agree if someone doesn’t maintain a system and it doesn’t work. That sounds like another opportunity to litigate and let lawyers earn massive salaries while the schmuck working a regular job can’t afford the vehicle, registration and insurance. Mean while the affected parties are never actually made whole. What a racket.
The MG does reasonable with adaptive cruise, but when a car turns away and dissappears from radar, the system slows down until it's sure the road is clear. It hasn't reacted to cars in another lane, but when there's a car parked in a left turn it might panic.
I use the cruise mostly to limit my exposure to speed tax.
the system should shut down with a sensor not working.
The only way self-driving is viable is if the car maker assumes responsibility.
btw, my mg keeps operating the brakes (if I don't override) for a few seconds after I switch off adaptive cruise. That avoids the car maker to switch off self-driving just before a crash and weasel out of paying damages.
Had a talk with an insurance assessor. He can't understand how so many cars with crash mitigation get involved in front end crashes. Fatalities might have dropped, but accident rates didn't.
Sorry. What's an MG?
Morris Garages, a once British vrand, but now chinese owned. I ahve ab MG HS which is basically a Chinese Escape but with a GM license built engine.
Yes, the automatic wiper is terrible. And manually operating the wiper is a 2 step process. Press the wiper button on the steering wheel, then use the left scroll button to scroll the wiper speed options. Heck, you almost always have to add a third step to look to the screen to make sure you selected your desired speed.
Even on a relatively well designed automatic wiper, sometimes it still wipes too fast, even while waiting at a stoplight. I tend to turn off my wiper at that time so that the wiper does not unnecessarily wipe the windshield.
Our 2025 Tesla otherwise drives beautifully. I don’t mind adjusting to having most of the controls on the centralized screen, it is what it is with Tesla ownership. I just wish the turn signal and wiper stalks were there.
