My son had a great idea, his first experience on the game and he asked if there was a skate park on the map. I did tell him, after remembering the days I was bored on a game and spent hours just launching cars from ramps on a skate park, that's a great ideas and the developers of the game are great.
one of the maps from skate 3 has been ported to the game: https://www.beamng.com/threads/skate-3-university-district.88531/
