He is probably referring to the Normal Cruise Mode (and not TJA) drive time when you see the Yellow and Red Hold Steering hand icons in the cockpit (not the steering wheel LEDs). This is when you have tap the steering wheel to continue the cruise assist, if I am not wrong.

I jest a bit since I am sure there is a happy medium, I am just trying to get a good sense about the sensitivity of the system wrt hands on the steering wheel since I know I could not get a long enough test drive to really understand this system prior to purchase .

Thanks for this great insight, it really helps. Now here is another one for you.... I know you can press a button to turn off the system at any time. But if the system is driving fine at highway speed, keeping your fingers/hands on the steering wheel as appropriate, how much manual force on the steering wheel does it take to regain manual control? For example, with the system on, if you decide to make a manual lane change by turning the steering wheel with your hands (and not using a button to turn off the system first), either a normal one or possibly an "abrupt" lane change, how much will the car "fight" you to maintain automatic control? Or will the car easily sense your manual steering input and return full manual control to the driver?
I am curious because during my X7 test drive, the Lane Change Assist was turned on and the amount of force the car turned the steering wheel seemed surprisingly high - and I even fought back a little bit when it happened. When exiting the parking lot, the car thought I came too close to the center line and abruptly turned the steering wheel to more aggressively get back into my lane (even though I had no concern with how close I was to the center line) - I promptly turned that rather annoying feature off BTW. That said, I like to think I am strong enough to overpower the car on the steering wheel, but who knows.....

The one thing I can say is that while every year gets better, the resistance has increased too. In my Q7 I could overpower the lane keep with just an annoying little extra hold. The BMW dies fight a lot harder but not so hard that it can't be overpowered. I am still getting used to the systems so I have everything set at medium. I may turn it down a notch but I am sure I won't turn it off.

I'd like to know how it knows. But I doubt it's heat sensors.

Am I the only one not able to get this going? Is there a step by step set of instructions in the manual or online somewhere?

You must be one of the lucky ones that lives in an area with no bumper-to-bumper traffic .... But seriously, my experience has been that the system can be a bit picky at times when it comes to meeting the criteria for TJA. But in general, if I am on the highway at speed, driving in "semi-autonomous" mode, if the traffic slows to below 40 mph and stays there for 30-45 secs or so, the option for TJA will pop up in the dash. Then I hit the mode button and TJA will become active.

Yes, I have been away for some time and I am often the only vehicle on the road. I will try this again when I return and hopefully can get it to work. Thanks for the help.

So I am definitely a noobie when it comes to coding the car and all that involves. I’ve been reading on alot of what can be changed but I was curious to know if the traffic jam assist can be coded to work over the 40mph limit it has built in. Meaning can we can it to where you don’t have to keep touching the wheel every few seconds at say up to 75/80mph? I haven’t found any information on this. I have a 21 m50i due to get delivered to my dealer soon.

Last year, BMW spokesman Oleg Satanovsky acknowledged that BMW’s approach to ETJA at speeds up to around 40 mph, “may be more conservative” but defended it as a safety measure and cautioned that the driver remains “always responsible for control of the vehicle” with ETJA. He declined to say whether the hardware is capable of higher speed thresholds through an over-the-air update.

I’ve used the super cruise in a Cadillac ct6 and it is awesome. No reason bmw can’t do the same in their 100k+ flagship. I own a 16 platinum ct6 but no super cruise. Wasn’t introduced until my 18. I would love for this to be able to be coded though. |

In my experience it would have probably caused an accident hands free at 70mph with 07/2019 istep and earlier - it couldn't deal with steep bends and would sometimes misread road markings and steer off track, but with 07/2020 it's solid. Not 100% but very close. I've driven hands and feet free for over and hour at 70mph (hand next to wheel on knee) and the car deals with everything, even wandering trucks moving into its lane. I can see them allowing hands free as standard at greater speeds on the 'inext' models. Whether they retrofit to current models is another matter. |
