What's interesting is that I haven't run into that situation yet. In your example, I hear the car driving in from the right. And not always from the rear. If the car drives in from behind the right shoulder to in front of me, the right rear is more involved until the car is more forward. I don't get just a mono faux stereo split from the rear. At least I don't perceive it that way. I get right side left side information depending on the action. The only time I sense the most stereo involvement overall is the musical soundtrack part of the movie when it takes over and even that has instrument panning and fires all around depending on the mix. Other than that the rears are directional and have always fed me placement appropriate information. The very best movies I've listened for it believe it or not, is animated, such as cloudy with a chance of meatballs, monsters University, Franken weenie, etc. The action in that material really puts the sound stage to the test. The only thing I wish I could have is my rears a bit higher and a bit further back. Sometimes they are a bit too directional, but that's mostly in the seats outside of center in my den. Aiming the rears universally for seating and to widen the bar R/L without pulling it apart took some time. But as always, the best seats are center for sure.
