Resolves YES if Russell holds his Mercedes F1 seat for longer than whoever replaces Lewis Hamilton.
Resolves NO if Russell loses his Mercedes F1 seat for any reason prior (including leaving of his own volition) to his next teammate.
Resolves N/A if they both lose their Mercedes F1 seats at the same time.
This is based on the time they both stop racing for Mercedes. So, for example, if in mid-2026 Russell is announced as a driver for another team starting in 2027 and then later in 2026 the teammate is announced as not driving for Mercedes in 2027, this would resolve N/A. However, in the example above if the driver lost their seat in the middle of the 2026 season (and therefore stopped racing in 2026) this would resolves YES.
Temporary loss of seat due to injury, suspension, discipline or temporary benching do not resolve this question.
This question may resolve when contract/news has settled it, rather than waiting for the driver to literally not race any more.
