Piquet has gone up a few notches in my estimation. Firstly, the disgraceful behaviour of Briatore at the last GP (leaving before the end because Alonso was out) really summed up how Piquet was seen and treated in the team. Secondly he whipped off his race suit to reveal a fairly big pair of bollocks by having a right old go at Flav both before and after he was shown the door.
I think given the right personal development he could have a career in F1. Shine in a Campos and everyone will forget what happened at Renault. Look at Button - rubbish last year, marvellous now. All it takes is a confluence of positive circumstances and suddenly you're a better driver, even though personally you're not trying any harder (maybe less so).
