> You have to absorb those bumps. But if you have no shocks you just rattle apart.

yes, and the real issue is, there are no smooth roads (ime anyways)

> Super smooth road with only left turns and is built to allow you to go as fast as possible?

whats interesting is, from a high-level perspective, riding with shocks (slack) can feel more like nascar than rally even if the day-to-day has bumps.

and of course, aside from slack, there are other things that help get to "nascar" such as good specs, good/easy architecture, low-interruption/async communication, and good management, but even then its just reducing the likelihood of bumps...
