Mini Clubman Cooper S parking break

Can't give any advice as I don't drive auto transmission cars but as many manufactueres are opting to do only auto transmission I might have no choose in the future.

The Owner's Handbook for my F60 says: "..Depending on the parking situation, the parking brake is automatically engaged...…….Steptronic transmission: engaging elector lever position P automatically applies the parking brake....."

I haven't experienced the parking brake being applied only when engine is turned off. I have had it in N (engine off) to allow the car to be rolled back and forth.

Have to say I have been experimenting with leaving the car in D at traffic lights, after coming to a stop, and just applying the parking brake, which then releases when I touch the accelerator pedal and the car moves forward. On occasion the start/stop also activates. It seems to be quite happy doing this. If one selects N it deactivates the Start/Stop.

I still have much to learn.
