Was going about 40-45ish mph on a back road when all of a sudden the brake warning light began flashing, and I had a fraction of a second before the car slammed on the brakes. The wife and 1yr old in the back seat were both fairly pissed. Thank god no one was behind me, because we absolutely would've been rear-ended. My guess is it saw a shadow of a nearby tree combined with a dip in the ground and decided to throw everyone through the windshield.

I can't stand these automated systems.

Until it actually saves your life.

I work in the machine learning vision industry and I'd be the first to tell you that the technology isn't perfect, and while false positives suck (and thankfully nobody was behind you and it turned out to be just an inconvenience), I'd still prefer having a CMBS than none at all.

This is purely anecdotal, but a few years ago I was driving for Lyft in my previous vehicle (which didn't have a CMBS) and had just dropped off a long haul up in San Francisco. I was coming back down the peninsula on the freeway doing about 60mph and I looked away just for a moment and suddenly noticed the traffic in front of me had stopped and there was no way I could have stopped fast enough, so instinctively I swerved into the lane to the left of me and thankfully there was nobody there. A CMBS would have definitely caught the traffic before I did. This is also a good reason why you should NEVER look at your phone while driving. I never have since then. That put the fear of the Lord in me lol.

You can adjust the sensitivity of the CMBS. I have mine set to short, and most of the false positives have stopped.

That won't work if it thinks there's an immanent collision.. We just need to get used to the few false collision detections it has.. I have driven over 70,000 miles and while they do piss me off when they happen - there have been three times where it saved my butt.. We have a lot of deer in our neighborhood and it saved me, today a dog I didn't see ran across the road while I was going 35 and I didn't have time to react and it saved him - that happened today.. Another time, I was doing 65 and someone pulled in front of me in the passing lane when I looked away for one second because my daughter was freaking out over a tiny jumping spider in the backseat. I will take the few false positives over the actual result that would have happened if I didn't have it at all. I am a great driver, but having the car watch out - I don't mind.. If someone hits me from behind because of it - then they were too close.. Get a dash cam with sound.. CYA

I turned off the brake portion of the collision warning stuff. You can change the settings in the menu. Having it randomly slam on the brakes was too annoying for me.

Are all false positives sudden stops, and how quickly can you re-accelerate after it happens?
You can accelerate fairly quickly.. I only had one oh shoot moment where I was afraid of what was happening behind me.. Mind you I was at almost highway speeds and at that point I was about to collide with someone else so who cares about the person behind me..

You would have to turn it off every time you get into the vehicle from my understanding - just be aware..

I have had the warning pop up many times. Perhaps it is my imagination, but with your foot on the accelerator it never seems to apply the brakes.

I've CMBS set to "Short", and RDM set to "Warning only" so it doesn't activate the brakes when I'm not following a lane marker.

That's intentional and how you can override any CMBS action according to the owner's manual.

Also it's good practice to keep the cameras on the windshield cleaned properly... It uses both camera and radar to recognize objects.

I've had zero positive positive warnings, and two false positives, both when normal following distance a vehicle and a sudden drop in the road followed by an upgrade.
