It is annoying that the car keeps turning the lane assit on after restarting the car. This option is great out on the highway, but terribly annoying in city environment. Sometimes even dangerous. When I go around a cyclist without a turn signal, the car reacts trying to get me back to the lane, which is dangerous for the cyclist.....

It sounds like it may be you being the danger. The lane assist won't work below (from memory) 50kph, and if you are moving out of your lane, you should be indicating anyway.

Aha !

A whole new can of worms.......

Should you or should you not indicate to go around cyclists ?

The answer is - it depends on the situation.....


One situation where you might make it more dangerous is, if the following car thinks you've indicated to turn right, and moves into the left lane, running the cyclist over. Especially in the dark, or at dusk, when the sun is low in the sky.

"Avoid indicating on each occasion that you’re overtaking a cyclist. This is more likely to cause confusion with drivers thinking you are making a turn at a junction or driveway. You must assess each situation and indicate only if you think the benefits of doing so will increase the safety of yourself and others."

The other can of worms being (and there are plenty):
Should you use your indicator and indicate religiously at all times?

Well. According to RoSPA, Advanced Drivers, Police Driver Trainers, IAM.... No.

:grin: Yep! Nothing like being enslaved and held hostage by the technology in your car!!! :smile_big:

I have a friend with a BMW, who switches off his Lane Assist on every journey (as you do), saying that his car wrenches him back into lane when he moves out without indicating! :grin:

Question. If as veeeight quotes, that you should not signal when overtaking a cyclist and the car throws you back, running over poor cyclist (that should not be in the road as they have no tax, insurance or road worthy certificate, goes on the path when it suits and goes through pedestrian crossings - Rant over), who is at fault, (apart from the cyclists that should not be on the road). Is the fault yours for knowing that without signalling can cause the car to cut back, could it come down to Mercedes for building something with risk, or the legislation makers that make up these rules not allowing for the new technology and how it reacts. Or could you just say "Sorry officer, but it was the car that ran over the cyclist, not me.", I think not. So with that in mind I am going to signal and if the car behind runs over the cyclist, they it is still going to be the cyclist fault. Or the motorbiker who was not there but decided to make a new lane in the traffic and try an squeeze past my pristine paint.

Driver is in control and in charge of the vehicle at all times.

You have to overcome the car steering if it throws you back into the cyclist.

If it's a solid white line - you shouldn't have been overtaking the cyclist in the first place!

If it's a broken white line, then you should just steer to counter the automatic system.

:)

You can override all these assist systems.

If the speed limiter or Distronic plus limits you, press harder on the accelerator.

If AEB brakes the car, just press your foot further into the accelerator if you don't want to brake.

If Active Lane Assist Steers you one way, just steer the other way overcoming the resistance.

If Active Lane Assist brakes you to one side, just steer the other way and either brake or accelerate if necessary.

Perhaps this is a bad habit, perhaps not but I was taught "mirror, signal, manoeuvre". Ie, you should signal before your manoeuvre, not at the same time as this gives other no advance warning of your intension.

To make this easier car manufacturers have added the "flick down" 3 to 4 flash function. This saves you having to cancel the indication when changing lane and was thought to be "a good idea".

Problem is, that in the Merc if you use this function, there is a distinct possibility that you will not have completed your manoeuvre by the time the indication stops. This kicks off lane assist and is dangerous. If the assist was set to give a few seconds leeway after indication stops then it would work much better.

Perhaps I'm the only one to use this function, but it was introduced exactly for this sort of manoeuvre.

I think it is supposed to know if you are intentionally turning the steering wheel.

This came from an American Mercedes website:

What is Lane Keeping Assist?How Does the Mercedes-Benz Lane Keeping Assist Work?
Veering out of ones lane, whether due to drowsiness or inattentiveness, is far too often the cause of accidents. It’s unfortunate when these are simple mistakes that could have easily been avoidable. Lane Keeping Assist is intended to warn the driver when they begin unintentionally leaving their lane so they can correct the error before it’s too late. A camera inside the front windscreen takes a look at the road ahead and determines where the lanes are while a control unit monitors the vehicle’s positioning as well as the driver’s behaviour. Because of that, the system can pick up on intentional lane departures and other movements such as steering into a bend, sudden acceleration, pulling onto a motorway, etc. and then will not alert the driver that they have left their lane.

That is my experience.,

When you let the car gently veer onto the broken or continuous lines, the lane assist will respond.

However, when I was driving on a winding road and delibrately crossing the centre line (no signal), the car did not react.

I think there is an explanation the handbook like that on the American website

Hi all, just wondering if anyone else has experienced this. I was driving down suburban residential London Road around 25/30 mph and all of a sudden felt like massive push from the driver side, the car slowed down slightly and on the dashboard a picture of the car and on the whole driver side it glowed red. I was just round the corner from home so when I parked up I checked the outside of the car but couldn't see any issue. Not sure if it's due to the active lane assist or something, just hoping there isn't an issue to be honest.
