Both my wife and I are F1 fans and make a point to watch the races together (which is cool!). While McLaren has no hope of winning watching them fail over and over this and last year due to Honda is heartbreaking.
The quality and design of each teams car matters a ton for winning. The drives of course are a huge part of it, however I strongly believe that you put Max Verstappen (https://en.wikipedia.org/wiki/Max_Verstappen) in the same Mercedes that Lewis Hamilton is driving he would be likely to win.
For those that do not know there are 2 titles here - the drivers title and the team title. The team title is the "Constructors Championship" i.e., they built the car.
