I recently wrote to Honda UK to voice my concerns about the implementation of RDMS and pointing out that in certain circumstances, on narrow UK roads I regarded the system as downright dangerous.
This is their reply:-
Thank you for contacting us and we hope your day is going fine.
We are sorry to hear about the issues you are having with the Road Departure Mitigation System (RDMS). The system itself is designed to alert and help you when detecting a possibility of your vehicle crossing over detected lane markings or approaching the outer edge of the pavement (into grass or gravel border) or an oncoming vehicle.
There are indeed some limitations of the system as mentioned in the Owner’s Manual - p.483-p.486.
There is also a way to disable the system mentioned in the Owner’s Manual on p.482, if you are not satisfied with the way the Road Departure Mitigation System performs.
The RDMS is turned on every time you turn the power system on, even if you turned it off the last time you drove the vehicle, as this is a safety related feature of the Honda Jazz.
If you wish to permanently disable the system, it would be best to speak to an authorized Honda dealer, as they are technically trained staff and would be able to advise you if this is possible.

Kind Regards,
Their rely doesn't tell me much that I don't already know, but do they appear to accept that there are situations where RDMS can have an adverse effect and suggest that I contact my dealer for help, which I don't think will be forthcoming!
All I need is the facility to switch off RDMS permanently, which would be the same as LKAS, can it be so difficult?
