I am trying to understand how to do the "Find Santa’s secret hideaway" achievement, in Post Apocalyptic Mayhem. Do you have any idea?

From this thread:

Start the winter map. It's easiest to turn around and keep driving until you see a raised platform with a house on the right side. Drive past it and turn around. Now boost into the left side of the house.
