Honda, Toyota and BMW served no purpose in F1 except to drive up the cost of competing for everyone else. I was not sad to see them go, and, in fact, I was particularly pleased that BMW did so after having fallen flat on its face. It seems karma didn't take too kindly to Williams being thrown under the bus.

Moseley proposed something similar before he got spanked into retirement. He suggested that F1 and presumably GP2, F2, or F3 institute a system of promotion and relegation similar to that found in association football leagues. It didn't take very long at all to see just how bad of an idea that was.
