Brake assistant works!

[mikikuki7]

So, I was driving to school right now and I was listening to music and I was sending a message, I never let my X5 get close to cars when I must send a message, I rarely text while driving.

I was getting close to the vehicle in front of me and the red car warning comes out and then I break a little more than I should and all of the sudden my X5 pushes the brake pedal even deeper. I was surprised because I didn't think the brake assist work whatsoever!

Just a little story to tell... I'm impressed

I noticed that when I get close to a vehicle and the red car warning comes up, the X5 is ready to break as soon as I step on the break.... I feel a bit of a drag even when I'm trying to keep it at a certain velocity....

This is good and bad. It's great that it kicks in to protect you in situations like the one you experienced. Luckily you're in Texas, so I'm sure you don't have to deal with snow in the winter months often. However, if this happens always with the braking system without the ability to turn it off and you are driving in traffic with snow and pump the brakes to slowly stop to avoid hitting cars/trees/rails etc, would the braking system kick in and cause you to slide? That's what I'm wondering. The braking system was kind of likethis on our 2011 X3, and it would cause the wheels to slightly lock and this was absolutely terrible in the winter sending our car slipping - it's one of the things I hated about the car because you could not pump the brakes at all without the braking system trying to do it's own thing, which led to overcompensation. Anyone care to shed light on this or experienced this with their cars if driven in winter? Thanks .

True, but I'm sure that the "intelligent" drive, would figure the temperature which would be below freezing and would compensate to make sure the breaks aren't fully pumped. I was far away from the front vehicle. I don't know why BMW doesn't specify how the system actually works. I'm sure they have their policies, but most of us knows nothing about it and it's bad because we love BMW. I wish I fully know how the system would work. I mean FULLY!

Yeah, it would be helpful to know the ins and outs of the system just to be safe. It might be intelligent enough, but you never know until you actually do real world testing .

It has happened to me 3 times and now I have set the collusion detection setting to late since it's very aggressive with the brakes..

I do not believe it. You are actually sending a text message while you are driving a two ton vehicle!
Is that legal in the US..text messaging while driving I mean not driving a two ton vehicle.

You are innocent until proven guilty here in the US.
I wouldn't do it and recommend to do it. But I do it when I stopped in the traffic light and non moving traffic.

[mikikuki7]

Well, I don't text. It's just that I needed to send a message. I was paying attention to the vehicles. I always drive carefully and I get the red car warning like 15 to 20 during the day. I just had never stepped on the break as I did today. It was a little more than usual.
Here in Texas texting is legal... LoL. People have crash into me and they're not even texting or on the phone! It's the driver and their driving skills! Unfortunately, the drivers here suck big time.

I text while driving! But I use Siri on the iPhone. Just keep the voice button pressed on the steering wheel and it kicks in instead of the BMW system. Works great

Yeah, I'm the guy behind you having to honk my horn when the light turns green because your head is down. Or the guy that's 5 cars back and don't make the turn light because your text was more important than everybody else's time or safety.
Is it so important that it can't wait a few minutes? If it's that important, then it must be important enough to pull over into a parking lot. If it's not that important, then it's not important enough to take attention away from driving.

Surely the ABS system stops the wheels from locking up, that's the whole point of it after all, or does the X5 come with a different system?

Well, if you are caught here in Norway (meaning being seen by the Police holding a mobile device or "something" to your ear) - you get what equals about USD 220 in fine. NO question asked!
Personally, having a car (and will surely soon get) a car with an outstanding Bluetooth option...I just cannot understand why you'd like to "challenge" that deal

Add those coins to a nice holiday and possible some beers on the beach instead! IMHO

Drive safely,
Bent

I certainly hope so. In the X3, the brakes would have a mind of their own when trying to pump brakes (the proper way to slow down in snow in order to avoid skidding), and this led to the brakes pushing on their own = a harder/deeper brake, which is a big "no no" in snow/icy conditions. By the description above by the OP, it sounds like the same situation where the car adds extra braking power to keep you from hitting someone.

Trust me, I have been driving since I was 10 years old. Even with doing that, I am still the one who have to honk and misses the left turn.
Regardless, I am pretty annoyed when someone is bothering me in enjoying my car. Unless if it is someone who is going to give me money to pay my living.

I guess we should all blame ourselves, human, for creating solution for a problem that is creating another problem which needing a solution.

[mikikuki7]

12 years driving and I have never, ever! Hit anyone! I don't need the break assist. It's the driver skills. Everyone should know their limits, but people just don't care. People talk on the phone and they drive 30 on a 45! To make it worst, both vehicles are traveling 30 on 45 using both lanes! I'm pro for people getting arrested while they drive using their cellphone for call or text. May be that way they will hurry up and drive faster!

So that's your justification?... You have to because it's part of your job? Sorry. You sound like a previous generation who regularly drove under the influence of alcohol. "I've been doing it for years and never got in an accident". Until you do. Or the old crowd who said they never wore a seatbelt and never died yet, so they aren't going to start now. Humans (even smart ones) don't process long term risk very well. If they do it 100 times, then they think it must be ok. You might get away with it 1000 times, but sooner or later...
Again, if it's so important that it can't wait a few minutes, then it is important enough to pull over.
If it isn't important enough to pull over for, then it can wait a few minutes. Nothing is important enough to put everyone else's safety in jeopardy. It's really not arguable.

[opasha]

Can we please get back on topic? This seems to be heading in a negative direction, unfortunately. The law is the law...whether or not you follow it is up to you, but as a decent human being, you should always think of others' safety including your own and not do anything that jeopardizes that. Most of us including myself are guilty of looking at our phone once in a while. I do my best not to do this anymore and tell my brother who does it all the time to stop because of real world experiences; I have seen crashes happen before my very eyes due to a split second of negligence. You may be the best driver in the world, but that means nothing when everyone around you could be a terrible/drunk/distracted driver - they are the ones causing accidents, which can and will impact you. That split second you spent writing a text could be all you need to save your own life if someone drifts into your lane or T-bones you when your attention is averted. I can go on and on, but I'll just leave it with this video:

If you guys want to discuss your opinions regarding this tangent further, please do so in PMs. Thank you .

[r33_RGSport]

@MysticBlue Great advise. Let's get back to the topic.

OP, it is a great feature, great to know that nothing happened.

I think you have a deep misunderstanding of how ABS works. "Pumping the brakes" was a technique taught years ago prior to the advent of ABS, but now that all cars come equipped with ABS it is (a) not necessary and (b) less effective than simply stomping the brake. If a skid ensues ABS does the "pumping" much more quickly and effectively than you can ever do trying to pump the brakes on your own. Actually the most effective braking technique is "threshhold" braking, where you apply a constant braking force that is just shy of causing the wheels to lock up and having ABS come on.

You may be right, and I respect your opinion, my friend. I guess I wouldn't say I pump quickly repeatedly; My braking is in medium intervals if that makes sense. I won't go deep into the brakes for them to lock up, but pump enough to slow the car down and then get deeper/hold longer as a I get slower. My description wasn't very accurate in the beginning when I explained. I'm not a novice in snow driving. I've done my fair share of trial and error with all four of our different weight/suspension SUVs to know enough about how to effectively drive in snowy Maryland weather . The X3, however, didn't respond correctly to such braking patterns that worked best on our '14 Acura MDX (19" wheels - all season tires), '05 Infiniti QX56 (18" wheels - all season tires), and '04 Infiniti FX35 (20" wheels - all-season tires).

I lived in Chicago, IL for 5 months for school also with my Infiniti FX35, and it handled beautifully during the cold winter .
