IAM & Lane Keeping Assist - view..?
Discussion
Having passed my IAM test over 25 years ago, and very proud of this, I wonder what the clubs/instructors view is of some of the new systems.
Maybe this might be covered if I had a recent evaluation/test, but just out of curiosity what is their view/guidance. I was taught, only signal when others would benefit, makes perfect sense.
However, new cars, will try and keep you in your lane, unless you indicate to change lanes, by tugging the wheel back to the center, sometimes like my misses Tiguan quite forceful, unless turned off.
So is it now taught to indicate all the time, or turn off the lane keeping.
This is a feature I hate when driving, and have to turn off, every time the car starts. Have read somewhere that if, in the event of a crash, 'safety features' were found to be turned off (might be permanently deactivated, it wasn't clear), then insurance maybe void.
What's the general view of features such as this these days, the same could be said about front collision, sometimes activates incorrectly, specifically with the club.

Insurance will not be invalidated if systems are switched off.
As for the IAM’s view on active safety systems & other technology, contrary to many people’s views, they’re not actually stuck in a 1950’s timewarp*. Examiners & observers are well aware of these systems & will take account of them.
If someone comes on test with me & they want to use lane assist, radar cruise control, speed limiters or any other new system, then I’m happy for them to do so, as long as they use them correctly. If, for instance, a signal is required to prevent lane assist from activating, we’re well aware of how the systems work and will take it into account.
On a seperate note, I’m very happy to see that I’m starting to get bookings for tests through again - first bike test of the year on Friday afternoon!

Lane assist tries to keep the car in the centre of the lane and so prevents the driver from taking full advantage of positioning around bends, improving the view or preparation for overtaking by taking the centreline etc. I will be interested to see how they deal with this. My solution was to not specify it after it causing problems on the test drive. It gets turned off on rentals.

I have a new Mercedes CLA and I hate the lane keeping assist feature...and would go so far as to saying it can be potentially dangerous under certain circumstances.
The changing lanes part does not bother me at all even though I do not indicate to move out when it isn't necessary, and never indicate to move back in when it is never necessary.
What I do hate is when leaving a fast road onto a slip road...if I have not indicated then one side of the car will be briefly braked and the result can be quite violent and is something you are never prepared for. It really does give you a fright and you wonder what the hell has just happened.
I have even had this system activate when in the right hand lane and in full control, but the car must think I am too close to the verge for some reason.
It really is a hateful system and I disable it every time I start the engine along with Start/Stop, which is even more hateful in conjunction with an automatic gearbox.

The IAM’s view. Well the IAM have worked with an academic and put out a survey on these vehicle assistances - if you receive their e-mails. I have responded, they have asked mainly about lane-keeping devices, and autonomous cruise control, but also about other devices. I don’t have those two that I mentioned. Unusually, the survey had several free-form boxes to write in.

The daft thing was, you could indicate right but change to the left and it didn’t seem to mind!
Only thing I can say to that is indicating to move back to the left after an overtake is completely superfluous, but the system surely cannot know the difference between simply changing lanes and leaving the carriageway onto a slip road, can it?Ron240 said:

I have it switched off in my own car, but it does not offend me.
A couple of days ago I was driving a new BMW; when I activated the cruise control on the busy M25 it also switched on steering assistance, and it took me a while to work out how to use the cruise control without also having the steering assistance. I hated it; every time I was overtaking or being overtaken by another vehicle, I tried to move within my lane away from the vehicle I was passing, and the system fought against me because it wanted me to stay in the centre of my lane. When steering round a bend, I felt (through my hands which were resting lightly on the wheel) the wheel move in a series of tiny jerks rather than making a single smooth movement. It had very strong resistance to changing lanes without indicating. When I indicated it switched off the steering assistance, so as someone else has said you could indicate one way and go the other.
By way of experiment into what would happen I forced myself to hold my hands off the wheel for a while - they were hovering just off the wheel, and I found it difficult to keep them off the wheel! After a while I had amber flashes on the wheel itself and on the dash. A little later the flash changed to red. I did not wait any longer. I have a firm view that I don't want steering assistance until it is sufficiently trustworthy that I can be holding a newspaper while the car drives me around!
Incidentally, the car can also change the cruise control or limiter speed as the speed limit changes - and you can set it to go above the limit by a fixed amount, with different fixed amounts for above or below 40 mph. I have it set to offer the cruise control change when the limit changes, but not to activate the change unless I press a button on the wheel to confirm. I have limited experience so far but I think this is useful.

I'd include them as part of the decision making and commentary for a given section of road; Well painted DCW? LKAS on to aid lane holding.
Full LKAS Deactivated upon exit; Roads with offsiding opportunities or where a more flexible position is adventageous? Disable road departure mitigation as well.
That would seem to be the best common sense approach; Making full use of the systems where it increases safety, and disabling them where they become a hinderance.
As Reg mentions, It's moreso incorporating the systems as best you can to improve the safety of the drive rather than simply declaring them forbidden

Dual carriageway
DCW is regularly used (at least on this site) for Dash Cam w
ker(s), but I have never personally known DCW to be an abbreviation for Dual Carriageway. I have found that it is better to not use abbreviations at all on forum sites, unless they are in common use so everybody should know what they mean.
It is no hardship to type a few letters.
