Road departure warning

[Jazzik]

During a holiday in the Netherlands I discovered that RDMS can indeed be quite annoying.
So far I haven't had a single problem with the system for almost a year. Until I came across (many of) these kinds of local roads in "cycling country" the Netherlands:

The red parts are "bicycle lanes". Any idea how RDMS reacts to that?
We know what's coming so it's not scary, just really annoying.
Fortunately, RDMS gives up after crossing the line a few times but then reactivates after some time.

Driving through Germany and Poland, RDMS was finally able to rest again...

RDMS needs a simple on/off switch as it often goes against driver experience road positioning.

I shut it off on every start - available on all models i presume?

Well done Jazzik ,as a regular defender of RDMS,  to admit it can indeed be annoying with certain types of road markings  . I too seldom have issues with it in the uk or other countries I have driven in , but admit it can occasionally be twitchy in  certain  situations  - often due to road patching ,extraneous road  markings etc. 

Interesting to hear that  after a certain amount of time reacting to these markings  the system  apparently learns  that maybe the driver knows best after all and  moderates its response for a while. 

Could this be why some users immediately find RDMS intervention  unacceptable and always  switch it off,
while others get used to it.    Maybe their RDMS system learns that they habitually drive in ditches, and adapts to their driving style

Luckily on the HR-V the RDS is such rubbish it doesn't require turning off.
I gave it it's head the other day and nearly ended up in the ditch. Useless T.G!
I consider that if you need such a thing should you really be allowed out on your own?
Similarly the lane guidance, doesn't work. Just a slight 'twitch' on the steering wheel with no attempt to drive round a bend. But with a bright orange warning on the dashboard and a loud warning chime.
At least that was one thing the Karoq did properly. (unnecessary as it may be!)

Strange... Lane Keeping Assist System (LKAS) works fine in our Jazz.
On the motorway it makes driving very relaxed in combination with ACC (adaptive cruise control). Our car follows (even fairly sharp) curves well.
When the traffic is not very busy, we drive with ACC and LKAS as standard.

It's what your requirements are.

I just wish the EU regs hadn't dictated it is on by default each journey.

Totally agree, it needs a switch to permanently disable it, at the drivers discretion.

My main concern is with narrow country lanes, where one has to pull in close to the verge to pass someone.
To have RDMS try to steer you away from the verge and into the path of the oncoming car, is to my mind downright dangerous and I just don't know how it can be considered a safety feature ?

[peteo48]

I agree Kenneve.

I don't go down country lanes that often but I did recently and it's quite scary (I normally switch it off but I had forgotten on this occasion).

Defenders of RDMS say that the twitch of the steering wheel is easily overcome but it's disconcerting and can induce momentary panic. It has zero safety benefits from what I can see.

I'd like a simple on/off switch. I have mastered how to do it now but it's a bit of a faff.

...is to my mind downright dangerous

We know what's coming so it's not scary, just really annoying.

It is clear that the interventions of RDMS are experienced differently by everyone...

At what speed do these systems become live?

[Thingy]

In July I had a 2 week holiday in Devon. I drove on roads of various widths, including some barely wide enough for the car. I had no trouble at all with RDMS.

[Lord Voltermore]

Am I right in thinking that a driver who cannot react instinctively to a slight twitch from the RDMS without panicking  has never driven on ice or snow?    And has been very lucky to so far  avoid unexpected twitches from loose gravel ,oil,mud, ruts  etc.   Long may it continue, but they are trusting to luck.  I would argue the occasional RDMS twitch helps  keeps you on your toes to expect the unexpected. 

Sorry if it sounds harsh  but would question my competence to continue driving if I couldnt cope with the RDMS  and LKAS twitches I have experienced so far over 7250 miles
It didnt try to steer me into ,or away from, a wild brown bear.  (which I suspect likes sandwiches,   A friend saw what may have been the same bear  a couple of weeks later  )   
,I mean no disrespect to my wife by saying that ,despite not having my experience of off road motorsport ,motorcycling and some advanced driver training, she has never had any problem coping with RDMS either.   

[ColinS]

Is that a bear right and you had to bear left to avoid it

[Kremmen]

RDMS seems designed for those who aren't paying attention to the road ahead and need a reminder to look out of the windscreen.

If you drive for the conditions and pay attention you don't need steering wheel twitches.

Using a post above, you make a decision to avoid a rut but it means briefly crossing a white line by a small amount. You can see it's safe to cross the line, nothing approaching, nothing behind, no side roads, but, you get the steering wheel wobble criticising your decision.

As you may guess, I hate it and it is turned off every journey.


For those who feel they need it or can ignore it, fair do's, we are all different.
