Michael Schmidt from Auto, Motor und Sport spoke with Michael Andretti:
“The whole thing is actually no longer an Andretti gig at all, it’s a factory operation by GM. And in fact, all the people being recruited, even in the chassis area, are now already being recruited by General Motors and no longer by Andretti.”
But since it’s a business, antitrust laws apply. There are suggestions that unfairly closing off market entry, Andretti may have a good case at its hand, now that his team cleared the FIA sporting rules. Previously Michael Schmidt also referred to a EU court case in that area but didn’t specify which exactly he means. I found one from 2008 about some motorcycling competition in Greece but don’t enough of the legalese to confidently say that this is it.
I hope that works out
