You guys remember the early days of anti-lock brakes on cars? They'd been around on aircraft and trucks for decades, but went mainstream on cars back in the '70s I think. I'm unfortunately old enough to remember the backlash and outcry against them, because of how intrusive the brake pulsing felt against your foot when the system engaged, and there was concern that they'd be expensive to maintain and that people would spend fortunes keeping them operational. There was even some insurance institute study claiming they saw no difference in claim data from cars with them vs. without, but who knows if their study and data were legit or they too were just concerned about the increased repair costs of wrecked cars with ABS systems. But the car mags and driving schools would have demonstration after demonstration, with experienced and pro drivers, and none of them could ever demonstrate stopping distances as short in cars without ABS as cars with ABS. Humans just couldn't pump the brakes as fast, and maintain directional stability as consistently, as the ABS system could. But the debate continued for years. Who here would buy an M car without ABS today, even if you could?
I'm not suggesting these add-on collision avoidance systems are the same as ABS in terms of necessity or function, it's just food for thought. |

i have mine on EARLY WARNING.
i get a CAR IN RED icon on the dash often, never had the brakes activating. i dont mind it, the light comes on and flash for couple seconds and it does not do anyhting i think it only activates the brakes if it did not sense any feedback from the driver while the light is on. there is a grace period, however, if the car senses that the steering wheel position is changing or you are braking, it will not activate the brakes. it's a pretty neat system.

I drive a MT and never had it apply the brake. I have seen the warning light come on a few times, and the audible sound only once or twice (when it was really close). So fairly unobtrusive so far (latest setting).
On the track I have to disable it every session, but sometimes midsession I'll realize the warning light comes on and then I have to fiddle with it on a straight, but so far no automatic braking. |

Yes, again I agree with you. Quote:
Haven't had it go off (auto braking) on the M2 yet because I'm driving it more carefully as it's still a new car and I'm carefully breaking it in, or I remember to turn it off. Have had the visual altert pop up once or twice though.

Yes, and I despise it, rarely use it. You think that's why the CA might work differently?

Correct. ACC + KAFAS has different intervention parameters than KAFAS alone. 2 major differences are the Deceleration Rates and Operating Speed/Closure Rate thresholds.

My son just upgraded from a 2016 M235 to a 2018 M2. He gets it on Saturday. I didn't get a chance to ask if the M2 is any different to the M235. Obviously it has the collision warning and braking. Does it have lane correction or does it just vibrate? Does the dynamic cruise control keep distance in addition to speed? We are also getting a new G05 (2019 X5) which I heavily optioned and has a lot intervention. Just curious how far they have gone with this 2018 M2.

I "really" enjoyed taking his M235 (w/ MPE) out on occasion. it always put a smile on my face. Haven't driven the M2 so I trust it will produce that same reaction. Really looking forward to driving it on Saturday. Last edited by X54TH; 12-09-2018 at 07:30 PM.. |

I'll get the BMW Genius to thoroughly take us through the M2 to better understand the features and the ability to adjust or disable. I know he hates that stuff in rush hour traffic. Hey, appreciate the heads up on the G05. I know our F15 stays off when we hit button. My wife hates the Start / Stop feature. I'll have to see if that can be coded. As for the CA / LD, I hear a lot on the G05 Forum how these features almost caused accidents as the car misinterpreted the road / situation. |

Interesting.
When I first got my M2 I got a little steering vibration and had collision avoidance kick in 2 times. First time it surprised me & I wasn't sure what happened. Second time I forced it into action intentionally just to be sure. Since that time, I have not had collision avoidance kick in at all. I occasionally notice the wheel vibration when I get lazy and don't use the signals. Regardless, I certainly do not feel like the automated systems are driving the car. While I focus on driving when behind the wheel, I'm not beyond screwing up so I leave them on while on the road. |

Guys, this is an alert system, there is nothing autonomous about it. It does not "apply the brakes" it essentially taps the brakes to set the pads and reduce braking distance. I have had it happen 3 times and don't like it but it is not autonomous in any way. The first time it catches you off guard (all three times there was no obstacle) it scrubs a tiny bit of speed but nothing of significance if your on the accelerator. If you're already on your brakes it is not an issue of course. I did take my car in to get the system recalibrated and since then I have not had any brakes taps and only a couple of alerts. These camera systems suck, my wife's Accord alerts constantly.

It's at its least intrusive setting already so I'm seriously considering disabling it but knowing my luck.... Perhaps I'll do what u did and try to get it recalibrated... |
