she isnt doing that well in either indy or nascar. shes just an average driver on good teams.
but f1 really lost their chance to grow here after the indy incident, that with people not really caring much about they "f1 crowd" makes it a tough sell here in america. nascar/indy/alms/grand am/etc all seems to have found a niche group to stand behind them. f1 would have to steal from one of those groups and i just dont see it happening.
