The cameras offer 360 degree coverage around the car.
The forward looking side cams absolutely see at 3 and 9 o'clock Again see diagram above.
It's my hope that the HW3 upgrade enables the 360-degree camera view. My guess (and it's not based on anything) is that the faster processors on HW3 enable realtime image stitching and simultaneous display of as much of that camera data as needed to make the full 360-view.
That's my wife's biggest complaint about the Model 3 -- her Buick can do it, why can't the super-advanced Tesla?
