If it was more than just “visiting”, I can’t blame him. If Ferrari let him go and he can’t get a drive with a decent team, I wouldn’t blame him for trying IndyCar. If he does, he may not dominate but I think he would do okay. He would at least have more time to get to grips with it than Rubens will.
These cars are much different than Formula 1 so Rubens is taking some time to adjust. No tire warmers, no power steering, they may be open wheel but they’re a completely different animal.
Massa would be welcomed with open arms to Indycar if he decided to make the move over. I would be excited for one!
