Gravity sucks, yeah? Heavy cars are sometimes too sltnogry attracted to the center of the Earth for their parking brakes to restrain. (Of which, BTW, you have now learned the importance: the parking brake won’t always keep your car in place, but it beats not using it and seeing the car rolled down the driveway )My Jeep Wrangler did this, but I could put it in first gear (manual transmission) and it would basically stay put. When the weather was bad I put a brick behind the back tire. You may not be able to get your key out if the car is in gear: I’d ask the dealership about that too.Ice anywhere near a tire could be very bad- try putting just one foot on some ice and see how steady you are- and on icy days, I’d move to California.Or park on the street.Except that I already live in California.
