Surely, the beauty of sidecars is the relative unique flavour of each and every rig. This lack of uniformity is part of the attraction. Whilst some degree of science and mathematics potentially offer some solutions to severe problems such as mishandling and inadequate engineering, there is much to be said for the outcomes of personal preference.
However, even if a sidecar outfit doesn't appeal to my needs, I still admire and respect the vast array of vehicles in the sidecar world. Long may it continue for it represents something that no "Volksrig" could ever satisfy.
