While I was reversing, I opened my door to take a look at the ground just to check whether I'm going straight or not. The gear automatically went in to Park while moving, making the car stop very harshly. In my head I'm imagining grinding gears. I understand there are some built-in anti-dummy measures so that people don't just walk out of their car while in D or R, but this sudden stopping was unexpected. Does this happen to you all? Sometimes it doesn't do this so I'm able to look at the floor while reversing. While driving slowly at 5 mph, if somebody (wife/kid) accidentally presses the P button or R button in the gear, would the car ignore this? The car should be smart enough to know to ignore these, but just curious if anyone knows for sure.
