I'm just throwing a random thought out here perhaps without the necessary political knowledge to be making such comment, but Roger is also the owner of IndyCar now. What are the chances he might try to sign Alonso on the condition of long-term commitment? This year's 500, perhaps some races after that, but also the full 2021 season? RP has all the necessary things to make it happen.
It'll get the global attention, and the commitment RP might want from Fernando for IndyCar and his team. Take it or leave it.
Perhaps I'm dreaming out loud, but I'm curious to see your thoughts on this perspective.
Alonso has stated many times he's not interested in running IndyCar outside the 500. Which is shame, because IMHO it would help him in many ways - getting the team gel together better, making him more attractive to top teams (like the aforementioned Team Penske). I don't think Penske would be interested in Alonso for just one season (and that too with dubious commitment, if Alonso manages to win Indy and fulfill his goals on his first run with Penske), RP is all about long term team building and doing what is best for him in the long run rather than short term gains. There have been occasions where he fired drivers quickly but that was only if he felt they are underperforming and there was a better long term prospect available (case in point - Montoya being shown the door when Newgarden became available). All signs are that he is now preparing McLaughlin as his next long term investment (either as a replacement for Pagenaud, if he doesn't renew his contract which is up at the end of this season, or for Power who hasn't been winning all that much lately. And for his +1 Indy 500 car, that's been reserved for Castroneves as long as he's up for it (HCN is still a member of the Penske family, racing for them in IMSA, and is chasing the record-tying 4th 500 win).
So, unless Alonso is willing to commit for the long term (3-4-5 years full season) i don't see it making a difference.
