it's more nuanced than that. shared/pool rides being faster is a function of distance (which is correlated to delays). from my experience (in LA), they're often no faster than buses for short trips (up to ~4 miles). between 4-6, it's typically breakeven. for trips over ~6 miles, shared/pool rides are usually faster (and gets more so with longer distances). but note that the bulk of bus trips are under 10 miles, so it takes some thought to get the best bang for buck.
