Yep.
I've been looking at the theoretical basis for how rubber tyres work
in full-sized cars - and it's an insanely complicated process.
However, one thing one learns early on is that the normal rules of
friction that we were taught in school were only ever approximations - and
they are very poor approximations for flexible, rolling things made from
long chain polymers with complicated sculpted surfaces.
In short - theory is useless - you need this kind of practical experiment.
