Noticed that I can turn the ship to look at a planet and I will warp away through it! Would be great if the ship automatically turned to the nearest 'clear space' when I click 'depart system' and then warp away.
Or you could think that since the ship is traveling in a subspace bubble, the ship can fly thru the planet because the bubble phases the ship into another layer of space while in flight
Basic warp mechanics negates this line of thinking. Maybe if the ship was equipped with a Phased Cloaking Device, a la USS Pegasus, it would make sense. Besides, the warp field doesn't shift a ship into subspace.
If warp mechanics did work like this, a ship would be able to travel at warp without having to operate the navigational deflector dish.
Edit: Oh, and personally, I just do the whole manual turn thing as well. Then again, I'm also one of those that flies into an RDD when approaching Earth Space Dock...
