Deactivate distronic plus while using cruise control.
Under scenarios like this, as the trailing car passes you, you SHOULD be able to change lanes into his wake. But if you do this, the DP feature slams on the brakes (which is completely unnecessary.)
Now imagine a third car 10 seconds behind the trailing car you are trying to blend in between the two car and all 3 cars pass the semi.
In this case, when DP slams on the brakes the 3rd (innocent) car is put in a difficult situation.
I, too, leave it off 90%+ of the time.
If you are signaling as you get into the car's wake, the car realizes you are flowing back into the right lane and the sudden hard braking usually won't happen. It immediately detects that the car that passed you is going faster than you are, even if it is only 1 MPH faster, and even if the distance is closer than you have chosen on the 4 allowed. I keep my distance control on level 2 (out of 4).
a) you look out the rear view mirror and see a car heading your way followed by a second car 10 seconds further back at same speed,
b) you observe that the car will pass you in 20 seconds,
c) you will reach a semi-truck in front of you in 25 seconds,
Any driver can manage this situation:: allow car to pass and pull out right behind him.
The way distronic handles this situation is to see the semi-truck in front of you just as other car passes and slows so you have lost you speed and if you pull out between cars you will endanger the second approaching car due to loss in speed.
Alternately, distronic does not start to slow as the truck is far enough away, but as you pull out behind first car dstronic slams on the brakes and endangers the second following car.
I turner Distronic off because of these situations. It is very annoying.
DISTRONIC, and cruise control in general for that matter, active steering assist and lane keep assist are as is in their name assistance systems that are designed to take over some of the driving functions while the driver continues to stay alert and in charge. They do not replace the driver and should really not be used when making maneuvers such as the above example. Use your judgment.
During my morning drive most are doing 80-90mph on 4 lanes, lane changing with maybe 1-2 car lengths gap (at best).
Distronic is literally worthless unless I want to get passed and cut off by the entire world.
It would consist of- I have 6 car lengths in front of me doing 85. Everyone sees this and closes that gap, car brakes and makes another 6 car gap, gets filled over and over.
With regular cruise someone could fill the gap and I cruise along with a few car lengths ahead of me and no constant/excessive braking.
Yep! These drivers are why we see 3 hour long stalled traffic jams due to their selfish need to get to their destination 3 minutes sooner, causing an epic crash. They are also TEXTING while driving selfishly. These are things that convince me fully autonomous cars are not going to be successful as much as I would love to see it.
