So the other night, morning since it was 3am, i was going to take my 540iA out. I didnt want to wake my parents because im pretty sure they wouldnt appreciate me being out that late. I didnt want to start the car in the driveway for fear of waking them up so i decided to push the car down the street some and then crank it. I put the car in Neutral and pushed it perhaps 3 feet before the car just stopped and it then just leaned forwards and back as if it were still in Park, but the lever was still in Neutral. Is this some sort of car theft safety feature? I love my car the more i find out about it.
