TsFp Getting past player clipping on Scotland the Brave

This trick is very simple, however it isn't very useful but is kind of cool

After the room with the gunboat go get the truck and knock down the fence, now decide where you want to go (you can get over the railing along the path that you drive on) This trick usually sends you back to where you were before performing it, however sometimes you can get a little ways of the map in your car.

To do this trick find the area you want to go and get out of the car, pick up the fence with your uplink and push the car over the barrier you are trying to get around.
then quickly(if you can) jump in the car and you should go past the railing now if you don't teleport back to the map, try getting out of the car which may also cause you to teleport back.

I've attempted many times to use this trick to get back to the beginning area of the map at the end of the road or on the hills there however the truck always goes flying away before i can get in..
