What is this speed limiter you're speaking of? What other Socialist Europe garbage did you come up with? It'd better not make it over here or on the cars imported to US
I didn't come up with any shit. I merely replied to a post based on publicly available information.

And what's with all hatred for Europeans? After all this is a European car brand forum.
It's just the EU not Europeans that will be impacted by legislation. European cars outside of Europe will actually be better and some models may not even be sold in Europe anymore because of this.

I'm happy with the speed limiters that the car already has. I have the choice as to whether I want to use it or not and when I do, it's because I'm on a road with cAmeras or average speed cameras(assuming I have got the cruise control on)

I think we all know that the system still is not 100% accurate as occasionally the satnav database may have the wrong speed limit for a road and that the camera may miss reading a speed limit sign or may read one on a parallel road. For example I regularly drive on the m25 here in the uk and it picks up on 40mpj signs on parallel roads and displays that instead of the usual 70 mph limit that is usually in place.

I'm new to BMW and just got a 2019 300i M-sport a few weeks ago.

One of the first things I did was turn off the lane-assist in iDrive. It scared the crap out of me and I can't imagine doing an emergency maneuver with it enabled.

This is obviously not BMW's doing but the EU.

If it turns out to be restrictive the I'm sure that it will impact car sales in the short term and have a big effect for manufacturers such as Porsche, Ferrari, Aston Martin etc etc.
I guess legislation like this should be challenged before the EU's Court of Justice as they deprive average citizens of their personal freedoms. I don't say over-speeding is totally fine and should not be penalized in any cases, however there is no direct link between it and number of road accidents. I believe regular checks on drivers' abilities like time of reaction, logical thinking, etc., even more frequent with age, would help us all better than installing all those nannies in our cars. Cause its foolhardiness and stupidity or lack of driving and thinking abilities that kills in most cases.

I also found this system dangerous for the reasons mentioned above. It's great on an urban road but throw in some potholes or a bicyclist on a rural road and it's dangerous. I turned it off since it's too aggressive. That being said I found that the vibration through the steering wheel to be not as strong as I'd like. On crappy American roads in the northeast, it's hard to tell if it was road noise or the wheel vibrating at lower levels below strongest. I also found myself floating more in the lane because the electric power steering doesn't provide as much feedback as to what the tires are doing. I think that's one of the biggest reasons that this type of tech is in new cars.

In comfort mode I agree but if you put in sport there is not more feedback but it's certainly easier to "center" for lack of better word

Make sure that you use your turn signal before you dodge that pothole or cyclist and the car won't fight back!

I actually found all of the modes, sport in particular as you mentioned, to return to center artificially quickly. When you let go of the wheel at the end of the turn it snaps back quite quickly rather than follow the tires trajectory and gradually come back to center. I think this is part of the problem and makes the steering darty. Again another reason LKA is needed.

Interesting, I found comfort steering takes artificially long to center while sport is about what I feel naturally it should do.

I wanted your opinion on this feature. Personally it would drive me nuts! I tend to switch lanes without using the blinker if there are no other cars around or when cutting across lanes during spirited driving. Guilty as charged, typical BMW driver.

I turned off the feature, and it still corrects the steering. Not sure if it needs to be coded out, but I don't like it!
I rarely use it because it does center very well. However, I do like the fact that it forces one to use the turn signal indicators. One of my pet peeves is drivers who turn but don't use their turn signal.

Have the LKA set on "warn when unintentionally leaving". Instead of warn late/early.
I can leave lane now without warning when I'm making active steer movements. So crossing bike lanes or switching lanes without blinkers gives no warning most of the time for as long I'm steering to do that.
But pointing the car in a direction and changing lanes with the steer in neutral does give a warning.

I didn't like it when I test drove a G20, I was on an empty road, wanting to switch lanes and it pushed me back. I imagine it's something you can turn off. Not promoting douchebag driving, but certain times you want to let loose (safely), and this seems like a nanny feature that would cause more problems than it solved.

Like when you need to swerve in an emergency if something falls off a truck and it tries to prevent you from doing it. This "safety feature" makes the car unsafe. You can turn it off but it is on from the factory and you may find out how to turn it off after it's too late.

A friend from the gym has had the same experiences picked up the car, LKA not explained to him (he didn't know about it) within a few miles he'd nearly crashed into a cyclist he'd driven round and the car tried to steer him back towards the guy, ended up fighting with it all the way home until he read the manual and switched it off.

Some of this tech is dangerous, then again BMW can't even get rain sensing wipers to work properly so it's no surprise.

It won't be long before LKA is sighted in accident reports....

SA should talk to client about LKA at delivery, I still don't think it's dangerous you can change the setting and it's easy to over power etc

I think we have to recognize that all of us on this forum are an exception, in that we are actually interested in what we are buying and might even bother to read bits of the manual to find out how to play with settings. We also, generally, have a basic understanding of what the various technologies do because we take the time to read forums such as this.

However, I'm pretty sure that 95+% of buyers are not like us. They just walk into a dealer and buy a car without really understanding its features and what to expect. I think those are the people who are more likely to be surprised by LKA, and won't even realize they can change the settings on it. They also won't know to have this conversation with their dealer at the time they pick the car up. I think dealers need to be aware of this sort of thing and pro-actively have the conversation when they hand over the car. I'm sure many do, but suspect not all.

How aggressive is this system?

My only experience is having it in a rental Benz that I didn’t know about but when it first activated it was more than manageable, dispute my surprise.

He is exactly that kind of user, it's a company car not his he just chooses from a list and really doesn't care, not a car guy at all he'd had a C class before so just swapped over because the G20 was newer.

If BMW are going to put systems in car that are going to proactively override the drivers input then they need to have dealers that explain this to customers.

LKA was the first thing I switched off in my 7 series but then I knew it was there.

Just picked up my new 330i M-Sport this week, and nearly hit a cyclist on the way home. Here in the UK the roads are very narrow, so I left my lane to overtake the cyclist and give him plenty of room. I was so shocked when at the last minute the car turned back towards him.

I've just signed up to this forum as a result

It's defnitely a feature I need to disable.

I had this happen on a highway. A vehicle parked in emergency lane, I moved to the left of my own lane to create room when passing. I did not cross the lane marker but came close to it, the car corrected at 130km/h (80mph) and it felt like I was deliberately steered into the broken down car on the emergency lane, had to jerk the wheel back to the left. The system freightened me. My girlfriend grabbed for the armrest as well. The guy standing by his car on the shoulder wasn't too impressed either. Turned steering intervention off after that.

I have an EU version, picked it up just last week. My lane departure warning only kicks in after 70km/h (43mph) I think, so I didn't have any issues in city traffic.

Before you guys disable you should try to reduce the sensitivity to the lowest level.
