that is some shonky statistics though, of course people who are annoyed by the lack of a physical button will be over represented in a thread about the issue. That’s like saying 90% of people in the new tyre thread are looking to replace their tyres. But that says nothing about the majority of MG4 owners.
Of course they believe you need to be able to turn off the car, hence the button in the seat.
As to why they haven’t also put in a physical on/off button, only the people at SAIC who made that choice really know why, and they probably based that choice on considerations we will never know. So we can’t objectively say it was wrong or right. All we can say is you are among those who don’t like it, and others are among those who do like it or don’t mind.
Like I said before, there are many other things I would like SAIC to pay an engineer for to fix before they put the off button two clicks deep in the screen instead of four.
