Both have handed in resignations even before testing, but are still working for the team?

Why not? It's not like they could learn any valuable secrets that could help the competition.

I like Alfa as a car manufacturer, sad to see them leave.

So sad to see the Alfa Romeo PR department leave. They contributed so much...

I guess with war criminals Aramco and Petronas being title sponsors for other teams, it could have been worse.

It's not but the rules say nothing against occasional posts about other forms of motor racing either.

Yep that’s all they do because it’s money over sport.

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.

And the deal also included the rebranding of the Renault PU as Cadillac. Andretti wanted to sell this as bringing a new constructor to the sport.

That's not true. They stated towards the press that GM will be involved in technical aspects without going into details but it's not really that hard to guess with parts those are:

GM has the facilities such as including several wind tunnels, aerodynamicists, engineers, and so on. At the very least the GM facilities will be used, potentially some personell as well.

Alfa Romeo is not involved in Sauber's technical aspects at all. GM's involvement will definitively be more than that.

I thought the regulations required any additional teams to use Renault engines since they have no customers?

Making a contract ahead of time was important to show Andretti has no yolo attitude about entering the competition.

There’s no such thing in business. All that means is that it would be extremely costly to back out at this point.

Yes, I know and he also said that. I don't have time and energy to translate the entire thing.

The current cars are also able to stay within the track limits, the problem is more that from the seating position the lines are hard to see and apparently the drivers rely to feeling the kerb vibrations to a large degree.

Ähm wofür steht das A in DACH nochmal?

Ich wusste es selber nicht, da habe ich Helmut Marko gefragt:

Dann müsstest du ihn Schweizer oder so nennen, denn er hat ja die geographische Einordnung verkackt.
