Lane Assist

[Jeffsm7]

Jazz Crosstar, 2023. Has anyone found a way to permanently disable the lane assist function? nearly caused 2 accidents recently with steering wheel snatched out of my hands and I am an advanced driver. God knows what it does to younger drivers. Very scary.
If not, I will have to delve in to the fuses, see if one can be removed, or the motor drive unit.
Would be an improvement if you could turn off either before or straight after starting the engine, but you cannot. You seem to either drive a few hundred yards or wait a few minutes before you can access the appropriate menu, then a dangerous manoeuvre to switch off whilst driving (I know, best to stop!!)
The car is beautiful otherwise, but this lane assist is a nightmare.

You say snatched?

I think we all found it a bit of a strange 'driver aid' when first encountered. I had never had a car previously that had it, so was a bit of a shock to the system when it first kicked in. However, once I had got used to its foibles, and understood when it was likely to kick in I was more prepared. The 'snatch' is nothing more than a twitch really, and nothing that your hands can't overide. It no longer bothers me, nor causes any concern.

Is this Lane Assist, which is off by default, or RDMS that wobbles the steering if you cross a white line without indicating ?

pulls the steering out of your hand if you cross a white line without indicating.

An antidote for RDMS is for the driver to give a slight jerk on the steering wheel when about to cross that white line. The car then knows that this is an intentional manoeuvre and not a dozing driver drifting into the middle of the road.

From page 309 of the MY24 manual ..... Road departure mitigation setting. Selects operating mode of the Road Departure Mitigation system.  Early/Normal/Delayed.

Check it's set to "delayed" which makes it less sensitive.

I've the same Crosstar.
Most safety features, of which you have any say in the matter, you have to deactivate every time you start the car.
I too, won't let it "grab the wheel" when I'm driving.
 I need to press different buttons half a dozen times, to get it to let me drive it like a normal car.

The saving grace is that it only flashes the speed limit if you exceed it slightly, rather than also give a beep! beep" warning like later models. That would have put me off buyng it.

And on a MY24 Jazz / Crosstar you can even disable the blinking:
Go to "Driver assist system setup" - scroll to "Traffic sign recognition system over speed warning" and select "off"
This setting will still display the speed signs the system has recognized but will stop the blinking.

Jeffsm7. When I joined the forum in 2021   complaints about RDMS and claims  it snatched the wheel  or "throws you into the path of an oncoming tractor'" etc. were  common.  Many posters confused RDMS with lane keeping assist.  In 2021 rdms  (Road departure mitigation system - which will also intervene if you unexpectedly cross  a lane marking or centre line)  the system was even  twitchier than on current cars and my 2021 car received a recall software update in 2022  which improved it,but your 2023 car should already have the latest version.
 
Many drivers were unable to cope with  any unexpected intervention and some still  switch RDMS off every trip.

But like many others I have learned to adapt my driving  to RDMS rather than 'opting out'. I too am an advanced driver (IAM)  and like others have said  if you  drive using more positive steering (rather than just letting the car drift to the edge of the road or across lane markings)  intervention is minimal, and any slight steering twitch  can be anticipated  , or if unexpected you can react to it quickly  without drama.

 I take the attitude there is always  a risk the car will   'twitch ' unexpectedly  in reality  , for instance  on  ice, wet/oily road, loose gravel , crossing a lorry rut  , on 'acoustic'. road markings etc.   You cant switch reality off , except by anticipating some as hazard awareness  or slowing down.   And the occasional unexpected  steering twitch helps keep my reactions quicker. 

I find driving for 'minimal twitching'  improves my driving .The only major change from what I was taught  is it helps to indicate before crossing a lane marking , even of there is no other road user there to see it. You are telling the car what you intend.   - And to do this you need to think more about what you are doing and why you are doing it  - an advanced driving technique.  I often dont indicate and simply anticipate there will be a slight twitch.

Apologies for any offence. Other opinions are available

So its encouraging bad driving. THAT's what I call a safety feature  NOT

There are many situations where you can smooth your journey on clear roads with clear vision for hundreds of yards ahead by cutting corners on slight bends

There are also many roundabouts where, with clear vision, you can steer a straighter path than follow the same circumference path as the white lines. Inside lane in, inside lane out, but almost clipping the roundabout

I used to do this on many trips and rather than follow my lane exactly I would take advantage of the 360 vision

This of course caused unwanted steering wheel wobble and the orange warning

I didn't like it so turned it off, but I accept some like it or have got used to it and I don't criticise others decisions

Under certain circumstances it can, in my opinion, be dangerous due to its aggressive nature.
 
Whilst I always have a firm grip on the steering wheels, there have been occasions on narrow roads, light restricted by trees, (sometimes wet) with poor road markings, where the steering has aggressively tried to pull me away from the Kerb(tree lined bank) into the path of a larger vehicle on the opposite side of the road. A road that is just wide enough for the 2 cars with a 50mph speed limit, the force of the correction could cause an overcorrection and a potential accident.

On most other roads, I've never had such issues, but for those rare moments, I now always switch it off as I am in control of my car, not the other way round.

I'm digressing here, but it reminded me of an occasion many years ago, when I and my wife took our CRV down to Cornwall for a holiday, long before, "lane assist."
On one day out, one of the small roads off the beaten track had uncut hedges both sides and there was only enough room for one car for a few miles.
The proximity of our car to these was beginning to worry my wife, so to try to deflect her concern, I said "It'll be alright. Look there's a sign up ahead, when we get a bit nearer, tell me what it says."

After about another fifty yards, she replied. "Road Narrows!"
