Looks like Kurt Bush is looking for work again. Evidently Penske is tired of his crap just like Roush was. Officially they "split mutually", but the reports say after the fines were handed down by Nascar, Penske was called to a meeting with the sponsor, Shell/Pennzoil and afterward Kurt Bush was let go. Weather Roger Penske had enough or not I don't know, but Shell/Pennzoil sponsors Penske Racing in both Nascar and Indycar, so I'm gonna assume they had enough and something had to change. And they are too important of a sponsor to make them unhappy.
I can understand loosing one's temper in the heat of battle, but it seems to be an everyday thing with him. Constant interviews, video, etc. is part of the job description and like it or not, he is the public face of Penske Racing, Shell, and all the other sponsors of the team. Plus, what they do is dangerous work, and I'm sure the other 42 drivers on the track have more to worry about than weather Kurt or Kyle for that matter, are having a good day or about to flake out and do something stupid. Supposedly he is seeking professional help, we'll see if it works, and weather anyone else is willing to give him a third chance.
