So I guess the answer is to protect idiots from them selves and protect the mfger from stupid lawsuits
That sounds more like the reason the feature exists.
The answer to the OP's question about, is there any way to shut this feature off is no, only workarounds such as LouM's suggestion of a seat belt extender.
I had disabled the seatbelt nanny before leaving the dealership when I bought my truck. There was no more alarm noise but the Evic would be briefly monopolized with a light show reminder about the seatbelt condition.
Then I remembered how well the seatbelt extender worked on a car I recently owned. I had bought that one primarily to kill the incessant beeping that never ended from the instant you inserted the key in the ignition unless you were plugged in. It was supremely annoying to me.
Also, the secondary reason for my purchase was the seatbelt receptacle was annoyingly short on the car and near impossible to easily locate while wearing any type of winter jacket.
So, I bought a short, rigid seatbelt extender for my RAM and couldn't be happier. No nanny alarms, no stupid Evic light shows that interupt my reading other data that I actually care about and much easier to install the seatbelt buckle while wearing winter jackets.
And, I can move the transmission knob out of park with the door opened, not that I do that anywhere but on my property and rarely at that.
AFAIK, using this type of seatbelt extender maybe the only solution to accomplish what the OP had asked for, unless you care to buckle the seatbelt and sit on it.
While I prefer to use mirrors, that was not the question.
