when I read "how it works" I assume you mean that it was a success? bailing out GM in the way they did pushed their novel vehicle platform technologies to fall to the wayside and for them to refocus on combustion. New brands were on the horizon, there was a hope for a new modern vehicular order but the midrange of the market was squatted by GM's insufficient vehicles. I don't think 2008's bailout worked, at all.
