If I understood the video correctly, the simple mechanical model is an inerter is the inverse of a spring. Analogous to a capacitor being the inverse of an inductor in an electrical model. Trying to find a better mechanical analog to the capacitor to optimize a passive suspension was the motivation because mass-damping suspensions had already been banned when active suspension got banned. But I probably misunderstood the video.
