I find the backup camera pretty useless the same way. I don't think I'd be trusting that to backup out of my garage anyway... it's probably only useful for parallel parking. I completely ignore it otherwise and yes the delay after shifting into drive requiring a minimum mph to turn off is irritating. I'm already half a block into drive gaining speed and the thing is still on. Knowing technology/software though, small delays like that are common. Even a webcam (which essentially is the same) requires "warm up time".

Nothing in the manual shows how to control the PDC/camera otherwise. Not even the volume of the beep tone if you have NAV. There really needs to be an option where you have to turn it on manually everytime especially because it's really just good for parallel parking in my opinion.
