Aggressive Lane change/Lane departure when using Driving Assistant Pro
I often use Active Driving Assistant Pro. option when driving on highways. It's very helpful and reduces driving stress. But I still think the automatic lane change when turning blinkers ON is very aggressive. Has there been any recent software updates that smooths the active lane change/lane departure function?
My 2019 X7 is with Software version 07/2019.39 |

Yes. Mine was very aggressive and after software update (not sure number, will have to check) where they kept car overnight, it now lane changes quickly after turn signal press and decently smooth. It still has a little "swing" to it compare to how a human would do it slowly, but it works much better now imho.

Its scary the first time you use it and that lane change is like a NASCAR-type move Its likely better suited for the Driving Asst Plus when you're less than 40mph as you want to fit in quick for Traffic Jam like scenarios.
For lane keep assist post-40pmh, they really should ease into the lane change less aggressively. Hopefully we'll see a software update address it.

On highway, what is scarier is once you pass a vehicle, and now ready to come back to the right lane, as soon as you turn the blinkers, the car just makes a quick lane change right in front of the other vehicle. I am sure it checks for the safe distance, but still its unusually close. May be its how they do it in Autobahn Germany, but in the US its considered unusual and pisses off the other driver I hope they fix that make especially on highway speeds. |

So here is a question for those of you with this option.... Is the lane change by the "computer" really that aggressive/scary? Or does it just feel more aggressive/scary because it is a computer making the maneuver and not you, the human?
I know that when I drive, I will typically change lanes very deliberately, but I wouldn't consider it too aggressive like you are describing. However, when I am a passenger with my wife, who drives very passively compared to me, even her lane changes can feel a bit aggressive at times, just because I am not the one in control of the maneuver. So in other words, is it merely a trust issue until you get used to the computer doing some of the driving on the highway? Also, can't you adjust the sensitivity/aggressiveness of the maneuvers the computer will make?

I felt the same way at first when I tried automatic lane change, but now I'm used to it and like the system "I'm making a lane change" mode.
Personally, nothing irritates me more than someone changing lanes or making left turns slowly, LOL. I'm glad my BMW gets me out out of a lane quickly and definitively.

We did have a 2400 mile road trip last week. The car did have a software update just before we left. I did use the Driver Assistant significantly on highways. It performed well. There were a couple of times the car was doing the ping-pong, but I think it may have been due to extreme wind gust... Once we were in Cali. I did use the Driver Assistant plus (trafficjam) options when the car met all it's requirements, I was driving hands free without putting my hands on the steering every 5 sec.The car did well driving hands free in the traffic go and stop.
I still think lane change at highway speed is still a little aggressive, even though I am getting use to it |

These driving assist hardware / softwares have some ways to go until they reach mainstream usability. I have had the Trsla Model S, X and 3 and to this day it is still unsafe in my humble opinion. I believe I am a much better and safer than the Autopilot system with Tesla and feel BMWs no different.

I'm on iDrive Version 2019/07.59. I took delivery from the factory on 11/15/19. So I must have just missed the latest update to iDrive. I don't know if the latest update is any better than what I have now or not. But, overall, on long trips or heavy stop and go traffic it works great! But there's trade offs. I suspect the brakes get used for more frequently when using Driver Assistance Professional than when a human is driving and paying attention. Maybe that's why the brakes wear out so much faster on these vehicles. I just did my first brake job on my 2008 Toyota Camry at 102,000. I bought the vehicle brand new and I am the main driver of that car. Their are pros and cons to all of this technology...Bottom line... "There is no such thing as a fully autonomous car". It will come, but we might not like what we get. Never rely on the vehicle, or any technology for that matter, to make decisions for you. They should be used as "Aids" only. Not substitutes. Just my 2 pennies worth of course... |

I also agree that the brakes on these cars will wear out quicker and are expensive. I did get Extended Maintenance Agreement on mine. |

I got the Extended Maintenance but I have not got the Extended vehicle warranty yet. That was expensive at the time. I think I may get that later by calling around for a better deal. |

So how well do the semi-autonomous features work at night?

Most of my driving using Driver Assistant been during day time. But the times I have used it at night time on the highways I have had no issues. Even during my long trips when it got dark I still continued with Driver Assistant; it does help reduce stress driving at night.

Relating to the high beams being in Auto, I don't think they need to in Auto for Driver Assistant. But I loved this feature when we drove on back roads at night in order to bypass a few major accidents on highway 5 going to Cali. I left high beams in Auto and the car did the rest. Nice and bright, and when system saw a vehicle or may be another vehicles headlight it shifted to low beam automatically and then switched back to high, all without any issue to the opposite vehicles or mine. The one thing I did not get a chance to test was, it's my understanding, that the car's Driver Assistant will use the iDrive navigation system (BMW NAV) to further help with driving, when you activate it, especially with the curves and other challenges. This is because my wife likes connecting iPhone Carplay and use Google map for NAV. |
