I've often thought that the way to do a camera-on-a-car panorama rig is to
space the cameras out in a line instead of trying (and failing) to put them
all in the same place. Then when you are driving around you shoot a panorama
by firing the shutters in sequence such that each photo is taken from exactly
the same location. The result would be zero parallax errors, but there would
be new errors with people and moving objects.
This would also fail slightly when the car turns or goes over a bump when taking
the images. Although the back wheels do tend to follow the same path of the
front wheels even when turning. If the cameras are very close together then this
would be minimal. But you would still have the bump problem. But to fill in the
nadir a 6th camera over the back of the car shot a little later would work well.
The GoPro are so small and if you removed the batter packs they can be packed
together even small, although you now have a problem of weather proofing the
cameras. Any small parallax error that still exists can be blended away most of
the time with a smart blender.
A smart blender works well for stills but for panoramic video with multiple
cameras a constant smooth blend each time is more desirable. The wiggle that is
created by the random seam-line placement from one frame to the next is more
distracting than errors in parallax.
