How to break any barrier in GTA IV with a boat

Just to let everyone know, it was very difficult for me to release this Grand Theft Auto 4 (GTA IV) glitch.

Why you may ask. Because you can use this glitch to get out of any barrier you want. In the video, I show two different places, but through further testings, we find that it can be used almost anywhere.

Put the boat against a wall of your choice and all you need to do is climb up and in the middle of climbing, press Y to fall. And if done correctly, you will go through the wall barrier and out of the map.

Takes alot of practice to get the feel of it, once you get used to it. You will be getting out of maps very quickly and very easily.
