I've held off saying this yet again, but here goes. This would be bad for the game. The game needs players in the air or in fighting vehicles for other players to interact with for the game to be fun. Encouraging players to sit idle on a hillside for 30 minutes, completely out of the game, while another player slowly flies a Storch, mostly out of the game, to pick him up would hurt the game overall.
Further, sitting on a hill for 30 minutes hoping to be rescued seems about as fun as watching paint dry.
