  In the framework of a Frenkel-Kontorova-like model, we address the robustness
of the superlubricity phenomenon in an edge-driven system at large scales,
highlighting the dynamical mechanisms leading to its failure due to the slider
elasticity. The results of the numerical simulations perfectly match the length
critical size derived from a parameter-free analytical model. By considering
different driving and commensurability interface configurations, we explore the
distinctive nature of the transition from superlubric to high-friction sliding
states which occurs above the critical size, discovering the occurrence of
previously undetected multiple dissipative jumps in the friction force as a
function of the slider length. These driving-induced commensurate dislocations
in the slider are then characterized in relation to their spatial localization
and width, depending on the system parameters. Setting the ground to scale
superlubricity up, this investigation provides a novel perspective on friction
and nanomanipulation experiments and can serve as a theoretical basis for
designing high-tech devices with specific superlow frictional features.
