I think that there is another issue that is contributing to poor quality images. It seems most apparent on the motorcycle shots and absent on the helicopter ones. There seems to be a large amount of chromatic aberration a lot of the time. This is where a lens system fails to deal with the problem that different wavelengths of light refract at different angles. The result is an image in which objects have a slightly fuzzy outline with a fringe of red or blue. This appears to be a characteristic of the lenses now being used on the tour motorbikes. The fact that bright, contrasty subjects (like a tour rider in team kit) are most prone to revealing this defect doesn't help. Compressing images that are already compromised leads to even poorer results.
