The latter is an interesting mindset to advocate for. In almost every other engineering discipline, this would be frowned upon. I suspect wisdom could be gained by not discounting better forethought to be honest.

However, I really wonder how formula 1 teams manage their engineering concepts and driver UI/UX. They do some crazy experimental things, and they have high budgets, but they're often pulling off high-risk ideas on the very edge of feasibility. Every subtle iteration requires driver testing and feedback. I really wonder what processes they use to tie it all together. I suspect that they think about this quite diligently and dare I say even somewhat rigidly. I think it quite likely that the culture that led to the intense and detailed way they look at process for pit-stops and stuff carries over to the rest of their design processes, versioning, and iteration/testing.

Racing like in Formula 1 is extremely different from normal product design: each Formula 1 car has a user base of exactly 1: the driver that is going to use it. Not even the cars from the same team are identical for that reason. The driver can basically dictate the UX design because there is never any friction with other users.

Also, turnaround times from idea to final product can be insane at that level. These teams often have to accomplish in days what normally takes months. But they can pull it off by having every step of the design and manufacturing process in house.
