Do you really think that rainy Canada is the same as Jedddah, or Singapore? And what is the purpose of the free practice sessions?

You’ve got the big bet to design the car between the season (which is kinda the big architectural decisions you make at the beginning of the project). Then you got the refinement over the season, which are like bug fixings and performance tweaks. There’s the parts upgrade, which are like small features added on top of the initial software.

For the next season, you either improve on the design or start from scratch depending on what you’ve learned. In the first case, It is the new version of the software. In the second, that’s the big refactor.

I remember that the reserve drivers may do a lot of simulations to provide data to the engineers.
