Three things that I think (just my opinions) will work against Andretti:
- A lot of people outside of NA fail to realize how big the Andretti name is in the US. Having Andretti in F1 will bring with it a lot of growth in the US as well as $US. But I think Europeans generally have trouble with the concept that a slightly smaller piece of a bigger pie is a good thing.
- The teams are afraid of losing their American sponsors to Andretti.
- The excitement that Drive to Survive brought to F1 and the corresponding increase in the value of F1 has peaked, so Andretti will be 'buying in high'.
I'd really like to see Andretti on the grid, but I still think there's quite a bit of struggle ahead before it happens.
