ACC Distance too far
Does anyone know if it's possible to make the follow distance any closer, either by coding or any other means?
My wife used to have a Grand Cherokee Summit, and the ACC follow distance on the closest setting was much closer than the closest setting on my M550i. Here in the SF Bay Area, the closest distance setting on my M550i is the perfect distance to have people cut me off all day long in medium traffic. The Grand Cherokee on the closest setting was just perfect so most people didn't cut you off or try to pass you all day long because it looks like I'm going so much slower than the car in front of me. Lol. I'm probably just going to have to deal with it but I thought I'd at least check. |

You can choose one of 4 settings using the button on the steering wheel.
Mine defaults to the third one which is about as close as I feel comfortable with in the dry, in the wet I set it to the fourth (furthest away). You repeatedly press the button to cycle through the distances and the car symbol will move on the instrument cluster / HUD to indicate which setting you have chosen. |

I don't know in that case but in my opinion the 1st and 2nd settings at anything like moderate or higher speeds are too close and if the car in front stopped suddenly , I have my doubts that the car / driver would be able to stop in time.
There is a saying "only a fool breaks the 2 second rule" to state that in the dry you need to allow 2 seconds between your car and the one in front for a safe distance. (More in the wet)It can be difficult to achieve on busy motorways at times as car will often pull in to the gap you have created. So just my opinion that even if it possible via coding I would strongly suggest not as I feel it would be dangerous. |

We have understood perfectly what you propose. In my country, and I believe that in all of southern Europe in general, we do not consider too much the rule of the 2s ..., despite having many miles of dangerous roads and with lots of bends.
It is not well understood that someone keeps so much distance with the car in front of you and even sometimes they overtake you from the right to fill the space ... I guess it is the policy of each manufacturer the standard safe distance. Surely official BMW dealer won’t agree to reduce it, even I doubt that it can be done by coding ... Oh, and I think the same, I would like to be able to adjust the distance a little more |

This is my problem with ACC in general, and the reason I opted not to get it for my 530e. Here in New York, driving is such a cut throat business that you do not have the luxury of a "safe" following distance. The moment you leave a safe gap, somebody will cut in front of you, and the cycle starts over again. You expand the gap again, and he next person will cut in again. They cut you off and not only will they not thank you, but they will still hate you and want you dead just for being on the road. That's just how a typical NY driver operates. Really sad.
I actually learned to brake with my left foot, so in dense traffic my left foot is hovering over the brake pedal. This gives me a slightly better reaction time and a bit more safety. |

To answer the OP's original question, I cannot find a way either. I am not a coder, but suspect that this is not an issue that can be changed with coding. Just have to live with it. I have adapted to it, and now like the system in general, but would also prefer a slightly shorter distance when using the shortest setting. For that matter, I wish it would just default to the shortest setting, so that I didn't have that extra step each time I turn cruise control on. But, hey, can't have it all I guess.

I was going to use ACC on highway only, I can't imagine myself drive in NYC too often, 90% of the time when I drive I'll be trying to get out of the city...

Again, I know nothing about this. Perhaps one of the remote coders could PM me and we could discuss it. I would love to code ASS to default at off, and the distance in ACC to default at minimum. Thanks.

I know your question has been about coding the distance but I feel compelled to prompt you to think about this.
If you are travelling at say 70mph with the acc set to the smallest distance , would be able to stop in time if the car in front suddenly slammed on their brakes? And if the road was wet? Just don't want anyone to end up in the back of the car in front should you be unlucky to experience that. Ok I've said my piece and will let it go now! |
