Bahrain this weekend.
According to the reports and pre-season chatter I have seen, the Red Bull was outstanding in testing and Max said that they've made it even more suited to his driving style. So unless they just missed on something (highly unlikely) it's near certain that Max will win his 4th championship and Red Bull will win another constructors' title. Checking my sports betting app, if you risk $100 on Max to win the championship, you will win $13.
The interest will again be on second, third, and fourth in the constructors and drivers races. Ferrari looked quite good per reports - and the whole company's racing operations have been apparently performing better than the past handful of years, so there's optimism . . . but also Ferrari.
