Exterior J-shaped door handles are cool looking but awkward. For smooth one-hand operation, you have to approach the handle from the correct side using the correct hand. (I cannot believe I am writing this. It reminds me of Apple telling users they were holding their iPhone incorrectly!) For the Driver’s side, use your left hand standing to the rear side of the handle. Push with your thumb and grab the handle that extends out with your fingers. For the Passenger side, use your right thumb and fingers standing to the rear side of the handle. You will get used to it, but your new passengers will not. It will make them feel stupid, which is not good.
