Road departure warning

[Neil Ives]

I mostly indicate when crossing the white line, more so since I got this car.

You should indicate well in advance of crossing the white line.  Indicators - there is a clue in the name, they should be used to indicate your intention to others before starting a manoeuvre.  It irritates me when driving down the motorway that a cars indicator starts to flash as it crosses, or even after it has crossed, the white line; utterly useless.

You don't need to tell me this. I'm one of the few, (apparently) who carries out Mirror, Signal, Manouvre

[Neil Ives]

When driving on a narrow country road where there may not be comfortable room to pass an oncoming vehicle the only safe thing to do is slow down, maybe even pull right over and stop until they've passed. I do this quite often; if only to make a point that they are travelling too fast and if they collide with my stationary car the fault will be all theirs. RDMS doesn't come into that scenario.

...Your LKAS continues working below 40mph?
The two white 'lane' lines stay white and are not greyed out?

Road departure warning I understand as RDMS, not LKAS...

... Yeah I thought Kenneve had moved on to LKAS  as he mentioned it starting to operate at 45mph.

Now, I believe RDMS on the HRV model, can be set to 'Warning Only'? If that is the case, then why is it acceptable to NCAP, to permit that condition on HRV, but not on Jazz, or are Honda making up the rules as they go along?

Who made you believe that? In any case, I can't find it in the manual of the HR-V.

I see the same description in the manual of my (and your) Jazz. You can switch it off, but nowhere is mentioned something like 'Warning Only'
See the pages from 453 onwards and on page 313 you see the selectable settings: 'Early/Normal/Delayed'.

I think quite a few of us are confusing the various systems and an action by one system may be  wrongly attributed to another.  For instance an oncoming vehicle or approaching a stationary vehicle may trigger the collision mitigation system yet be blamed on RDMS.

Some may argue that it doesnt matter what system is responsible, they just  dont like it.

     But it can lead to the wrong systems being switched off unnecessarily,  or the sensitivity settings not being correctly adjusted. Or they conclude the  adjustment had little or no effect because some things still happen .(activated by another system)

I do mirror signal manoeuvre OK,  but I don't indicate unless someone can benefit from signal, I see people who don't do the mirror bit ( or on a multi lane road 'the look over right shoulder bit' ) and think that by putting an indicator on it gives them permission to manoeuvre.... unlike German car drivers who don't even think they have to signal.

...It's easier and quicker to just MSM on every occasion as then you don't have to spend time assessing whether anyone will benefit or not.

If you are paying attention you should already be aware of someone who can benefit..... or not.  Doing something automatically while driving is never a good idea.

...360° x-ray vision isn't one of my fortes.

Your last statement doesn't make sense. The practice and experience of driving instills the notion of 'doing something automatically while driving' else you won't get very far down the road...

Agreed, it's easy to overlook pedestrians or traffic about to emerge from a concealed turning, if you signal then you're covered in all scenarios

This video on the Honda info site for RDMS, mentions the speed of operation and the 'Warning Only' setting.

On the sort of country roads I'm talking about, there are no white lines, only grass verges.

[Kremmen]

So who's going to start a thread with a vote addin for 'do you turn RDMS off or not' ?

Be interesting to see the figures.

Totally agree . And its something that is ,or was ,taught on most driving courses in the uk where you progress beyond basic driving lessons.  eg bus driver ,IAM, ambulance, police etc. 

Its a hard concept to grasp if you havnt been on such a course,or studied advanced driving from manuals.

Doing things automatically ,mirror signal manouver sounds good , and works well enough if you actually do it properly.   Ie look in the mirror and act on what you see  , and only indicate if its safe  and appropriate to do so,at that moment , and only manouver if its safe and appropriate to do so.   But too many drivers rush it . Mirror signal and manouver automatically  and dont actually look or think about what they are doing ,or not until its too late. 

Actually deciding whether you need to indicate takes it a step further. It encourages you to remain constantly aware of other road users and to read the road and  plan ahead that little bit earlier.  And if as a result of your deeper analysis of the situation  you decide there is no one to indicate to, you dont.

   In busy and fast moving situations where someone might appear unexpectedly  you err on the safe side and indicate anyway.  If you dont you are not doing it properly.

 But there are many situations where its obvious  there is no one else  about and indicating for the sake of it is a bit silly.
 In countries where its a legal requirement to indicate,  If you correctly deduce there is no one about, there is no one there to see your 'crime'.  but probably better to drive like the locals.      

Safe and experienced drivers may be doing it correctly without realising  it.

 I'd stick to what's in my (and your) manual and not get confused by what features are available in other parts of the world (in different cars).

Such debates re. indicating always tend towards the 2 positions of "do it always" and " do it if you need to". There is no right answer of course. However, while there are arguments for both sides, there are also many other rules of the road which are not optional and we are told to just do it. Perhaps the most obvious one is mandatory speed limits.
Those drivers who are, or believe they are, in the elite group will argue that they can drive at any speed they consider safe for the circumstances, in which case why do we have mandatory speed limits. If you are on a deserted motorway at night with no other traffic and dry warm conditions then why can't you judge it is OK to drive at 80mph?
I had/have issues with some of the dogma of the advanced driving groups, the most significant being the (now dropped apparently) mantra of "making progress" particularly for motorcyclist assessments. I always argued against that, and apparently it is no longer encouraged as it used to be, but many folk who go through the courses still seem to exercise this principle. I was obviously always wrong, but miraculously I am now right. I have always worked on safe riding rather than making progress, my mantra is "if in doubt, don't", 50% safety margin is better than 5%.
 
I stick to indicating as near always as I can manage, you just never know when someone will pop out into view and if you have already indicated it is one less thing to have to bother about retrospectively. It doesn't cost anything even if it doesn't achieve anything. YMMV.
