You can still launch ATVs. When I was in FEAR I lead a Fury Op. Ch0mp3r has screen shots somewhere of me being tossed from whatever our first base from sanc on Forseral to right in the middle of the cont, I flew for like 15 seconds hitting trees, rocks, walls. . .and I am not kidding when I say I was flying over a wall and heard a moan as if someone was stabbed. . .so I think I hit people too
On a side note completely off topic. . .I just realized that when I first started PS when a vehicle was almost dead it quit working and you couldnt operate it. . .anyone glad they got rid of that cause as an ATV user I sure am.
