In Indycar he doesn't.Just a guess... but perhaps because he doesn't want to drive ovals?
I don't think you could call Grosjean and outcast unless you consider Hulkenburg and Kobayashi the same way.I think referring to Grosjean as an "F1 outcast" is a little inappropriate. He was never rejected from the sport or ostracised from it - which is what an outcast is - as he spent 10 years in the sport.
He's probably a better driver, but Danica Patrick leaps to mind as a good example of this.
