Lewis Hamilton may have secured his fifth drivers' crown in Mexico, but the championship that determines how a large chunk of prize money is distributed between the teams is still up for grabs. It's also the title that team members' bonuses are attached to -- for example, every full-time Mercedes employee in Brackley -- from engineers to catering staff -- are due to receive a minimum payment of £10,000 if the title is won.
"It's the constructors' championship that pays the mortgage of the colleagues and pays for the Christmas gifts," Mercedes boss Toto Wolff said in Mexico.
