Cruising slowly through the neighborhood streets at less than 25mph, so I decide I was going to activate the EV Mode. Stopped at a stop sign, slowly eased off with my foot lightly on the accelerator pedal and finger on the (EV) button, and pushed it...*bing* Oops! Crap! I hit the Parking button as I was rolling off. I thought there'd be no problem but I noticed I was not accelerating when pushing the accelerator pedal... lights everywhere on the cluster (the car was still rolling) looked like the state your car is in when you push the Power button (2 times) without the brake held down...no "Ready" light. I'm still rolling on and immediately hit the Hazard lights (cars around). With my foot on the brake, I push the Power. Nothing. I try again. All shuts off (& Park activates). (My foot still on the brake) Pushed Power again...*bing!*..."Ready". Put in in gear and headed off.
I remember every detail of this moment. I didn't panic because I'm in a residential area, so its highly unlikely of "You might have..."
Anyway, I'm confused of why the 'engine shut off' while rolling slow after pressing the Park button. I thought normally it'd just chime a warning, but keep on going.
