On my Model 3, if the driver gets out of the car without hitting park, the car automatically goes into park. Then walk away lock (if using Bluetooth keys are being used) will take over. The ease of one-pedal driving (automatic hold at stop) and auto park when the driver exits has even gotten my muscle memory to just get out of the car and let it auto-park. I ***DONT*** recommend this and I try to remember to do it as often as possible, but it seems I do get out often without hitting park (and it's never not automatically gone into park for me but YMMV).
