With Honda's Hokey Cokey Formula 1 strategy set to enter its latest 'out' phase, Messrs. Horner, Newey and Marko have some thinking to do before presenting Red Bull boss Dietrich Mateschitz with a strategy which doesn't involve his Formula 1 teams playing second fiddle to a manufacturer outfit.
Mercedes is not interested in playing ball, while a customer unit from Maranello comes with no performance guarantees and a limited warranty. In theory that leaves Renault, the company with which Red Bull had a very public 'conscious uncoupling' after years of growing apart.
Like a divorced couple moving back in together just to pay the mortgage, it's doubtful that Christian Horner and Cyril Abiteboul would relish the prospect. They would soon remember why they split up in the first place.
