Michael Andretti is having a terrible time attempting to break back into the world of Formula 1.

Andretti, the 1991 CART champion son of 1978 F1 world champion Mario, has been trying to prise his way into the sport for more than a year but has been perpetually rebuffed.

First his attempt to buy Sauber fell flat. Then the sport offered him a lukewarm response to a request to enter as a new constructor.
