You press the engine start stop button whilst driving?

I'm imagining there is a safety mechanism in place which would prevent it doing anything above a certain speed or in D, but I've always been curious.

Nearly hit it by accident while switching off ASS and got me curious.

this has been asked and answered numerous times.

nothing will happen. I believe you have to press it twice or three times for it to actually shut off

Id like to know what happens if you throw the key out as you drive along!

I wondered about stop/start too, and what happens if you press P on the gear lever?

Says remote not detected and lets you drive anyway.

I had a strange one the other day where the screen said the engine may start upon pressing the button even if my foot is not on the brake.

Tried that. Just says must be stationary.

You need to hold the start button down for a few secs for the engine to turn off while moving.
And I've taken the keys out of the car loads of times while the engine is running (idling) and nothing happens.

Oh man that could be catastrophic.

I fudged a gearbox on a courtesy E320cdi once by chucking it into P at about 20mph.
wheels locked, car slowed to a halt and before it even stopped I heard a clicking noise then a thud.

I told europcar I had no idea what had happened to it and that I thought brand new Mercs were meant to be solid.
they sent me another one within the hour!

Good to know.

Sounds like BMW have thought this one through, unlike Merc!

I came to a stop at a junction and pressed the stop/start off, in fact I turn the car off...
