My settings are:

CMBS - On

VSA - On

RDMS - Always off

LKAS - Always off

ACC - On when no traffic around or it’s all moving at the same constant speed with nothing to scare the software, switched off as I approach other cars if not.

I did ask Honda about the issues some people are having, but they just replied that they have no plans to look at the software.

...It's a pity they don't seem to be bothered.

Perceptions of the effects of  these systems is subjective and maybe its not for others who have no problem to suggest some drivers may be over reacting, or need to change sensitivity settings or 'get used to it'.       
But they may be over represented in  consumer reviews etc.  Reviewers are much more likely to report things they personally dont like  than they are to mention things  it never occurred to them not to like.

Honda probably do listen to complaints but,like most businesses ,are more likely to quietly fix things rather than admit there is currently a  problem.

Drivers have complained in the past about various ' new fangled' safety technology. An experienced driver can stop more quickly in snow without ABS for instance. . I'm pleased to see the Honda system Automatically disables ABS at low speeds.

Traction control suppresses engine power which can cause problems when trying to get out of deep snow, sand, up inclines etc, . You can switch it off on the Jazz.  On many cars you cannot  switch it off, or have to pay silly money for a 'sports' option.

 I have noticed a few Driving schools   using Hybrids.  The Grumpy old man in me thinks "too easy. I didnt even have proper synchromesh. Its character building ".
Apart from the obvious  problem that they are only licenced to drive automatics , what of the new driver aids?     Will they suddenly be phased if driving a car that doesn't try to  stop them driving into ditches and the like?         With ongoing  improvements in 'self driving' technology  will there soon be need for a further class of driving licence that only allows them to drive cars with the necessary technology ?

...If nobody put forward that notion then it would just be people complaining about what they perceive to be a problem or danger which, unchecked, could then lead to the consensus that they are indeed correct as nobody has questioned them or put forward an explanation/alternative. People can overreact, it has been known.
The playing field isn't level and never will be.

A wayward Jazz hybrid as a driving school car sounds like a potential nightmare  :o

NCAP is going to be rating the performance of assistance safety systems.

No entries for Honda at the moment.

Are you sure? In Mk3 Jazz the VSA-off button just gives more freedom to spin wheels but will limit the slip eventually. There is a procedure to get it completely off, but that's not instructed anywhere by Honda. https://clubjazz.org/forum/index.php?topic=12099.0

I have only based it on the following from  page 421 of the mk4 online manual   

" When the (vsa off) button is pressed the traction control function becomes less effective.This allows for the wheels to spin more freely at low speed ."

 I hadnt seen your previous post about completely disabling the system to allow for more fun with more spirited  wheel spin. (been there ,done that.  ;)  I'd sometimes  put the car into a controlled slide using 'handbrake turn'.  That wont work with electric handbrake.)

My main concern was getting out of mud and snow.    I used to compete in off road trialling (in a car) where you often got stuck in mud and snow.  We sometimes needed to spin the wheels at maximum revs to blast away loose  mud and snow revealing  a better surface.    My hope is that the basic VSA off switch will still allow enough wheelspin for that.   The instant torque from the electric motor may help.

Low powered cars with winter tyres are best - the MK1 and 2 Jazz pretty good  without winter tyres and could drive past many others in snow, but with winters they are unstoppable ( only limit is ground clearance ),  better than the civic with winters on, instant torque is not what you want in slippery conditions, that is why a CVT my wife had was good in snow even with normal tyres as it selected the highest possible gear.

Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

I had a Bedford HA van for a while when I was a telephone engineer. The engine was pretty gutless, however one winter the world was bogged down with snow and many telephone cable were pulled down by a thick coating of frozen rain. Us phone engineers were working overtime putting the lines back up. My little HA van was superb in the snow. Low power means less chance of breaking grip.

Same as the Hillman Imp. Engine weight over the drive wheels. They could climb snow hills where normal front engine rear wheel drive had no chance.
Let's be careful out there !

That's why BMW now has front-wheel drive (and 3-cylinder engines)...  ;D

I traded mine, (2019 Series One) in for the Jazz. The car is based on the Mini Cooper S.

RDMS always off for me. 8)  ive said before, its nowhere near as well developed as it needs to be to use safely.  The similar system on my 2nd car, a Golf, is loads better, and I leave that one turned on. 

re winter tyres - whats the best option for the crosstar?  I had a look a while back and couldn't find anything I liked, as I wont buy a noisy tyre, and a lot of the budget brands seem to be quite noisy- road noise

I've been keeping the RDMS on because the nature of my motoring - short journeys, stop starting etc etc makes it a bit of pain and I'm still not completely sure how to do it despite the many excellent explanations on here. It takes absolutely ages for the seat belt screen to disappear. I managed to get the system to display at one point whilst on the move but couldn't work out how to make it go from green to white. Pressed the home key - nothing.

Did a 5 mile trip this morning - it was wet. I have to say it was "doing my head in." The following occurred.

1) A white steering wheel with no twitching of the steering wheel. No obvious cause. I don't even know what this is.

2) The dreaded orange steering wheel with associated steering wheel twitch. No obvious reason for this. I wasn't overtaking, I was in the right lane. I suspect it might have been a join between 2 pieces of asphalt - I've had this before and, I think, Kremmen has as well.

It's not great is it?

The seat belt display can be instantly dismissed by pressing the home button.

There are more than one seat belt displays so you'll probably need a few presses to get to your set/preferred home display.

If you've set the display to show 'icon and words' then you see the 'dismiss' message to prompt you to press the home key.

I really can't do any more than my series of pictures. I can turn off RDMS in seconds now. I forgot once but now it's second nature I did it whilst driving.

As you say RDMS is a real pain. It's big brother gone mad.

I forgot to turn mine off this morning and it tried to put me head on towards oncoming traffic on a humpback bridge!

It’s good to hear from the HRV review that dealers know about all the complaints with the Jazz system. Honda also mention in the marketing that the HRV has an improved system too.

Hopefully they can do something with the Jazz system via software update.
