Can someone move my car if it's in Park?

Question

If I'm parked on the side of the street, is it possible for someone or a group of people to move my car by pushing it for example? My car is an automatic and it was on Park with no hand-brake on packed snow/ice.

Setting : My car got a ticket for parking in front of a driveway. I'm 99% sure I didn't park in front of that driveway as when I parked, there was a lot of other places on the street and the driveway in question is really hard to miss. Before pleading not guilty I am trying to figure out if it's possible my car was moved by someone. Police said that I was in front of a driveway and that my car was so close to someone that they were not able to move, which wasn't the case when I parked there in the first place and when I got to my car there was no car around mine. My guess is that someone thought I boxed them in and pushed me in front of a driveway with their car.

Answer 1

Cars are slideable even if in park, when standing on level snow/ice. It's not easy (the pushers have poor traction, too) but it's a lot easier than when the car's on dry pavement.

Answer 2

Does not even need to be pushed or slid - 4 or 5 men can easily pick up a small car and move it...

Did it with 4 others at school when we moved a teacher’s car so we were only 15 at the time but all in the rugby team... wish I still had those muscles...
