Maybe you have got the wrong car for you. 
This seems to me to be an offensive and pointless comment.
I would like to think I am just as free to give my thoughts on the subject as you are, of course.
The subject is: "The most pointless feature of a Honda Jazz".
I think there are several equally pointless features.
I have owned Honda cars since 1979 (several of which I have owned for 10 years or more). I recognise Honda's very high engineering skills.
All motor manufacturers get carried away with what I, personally, consider to be pointless features which, to me, add little benefit and often real nuisance and even danger. I appreciate others may enjoy/ need them.
I tend to know if the car door is open, the keys are in the lock, whether I have my seatbelt attached, how I am working the engine.
I do seriously question whether anyone without this basic awareness should be driving.
Some features on cars, I think, can probably be positively dangerous - particularly the Eco light which is a real distraction. Please, eyes should be on the road not on the fuel tank.
I selected this Jazz very carefully on specific and demanding criteria against offerings of half a dozen other manufacturers' cars in the same category.
The Honda Jazz matches my needs extremely well despite the many features which I find completely and utterly pointless (frankly, sometimes very annoying and, even, potentially hazardous) but which other people may find very attractive to their needs. Life is full of compromises.
The answer to your query is No.
