Creating new vehicles can be very funny and extremely helpful if you want to finish the game quicker. This guy brought the game to another level by hacking it.
First he builds a small ramp truck to show us that it is possible and then, after a few seconds, he replaces the small ramp with a huge one and in things way he makes the game much easier!
He should have shared also the trick so we could build a ramp truck by ourselves. Amazing!
