I was at Home Depot and barely awake at 6am and when I came out I saw my Mirage had rolled a few feet and crashed into an old Jeep. The guy was sitting in the jeep and his car had zero damage, mine a light scratch.
But it could have ended very badly. I cant believe I would make such a foolish mistake. THis was in Florida, no hills just flatland but there was enough slope for the car to roll forward about 4 feet.
Thats why its smart to engage the parking brake AND ALSO to leave the car in gear. I tend to leave it in Neutral and just engage the parking brake (Not smart).
I hope others can learn a lesson from this event. Always leave car in gear when parked PLUS put on the parking brake.
