In all seriousness, I think the people under Jost Capito thought to better make something simple that works and evolve from there than to get lost in details. I think getting lost in too many details is where Mercedes’s comments came from that they sometimes don’t understand why the car behaves the way it does.
It’s actually a pretty smart approach for a team with limited resources. Building efficient downforce is very hard. Building efficient low-drag is much easier. You will suck even harder at most tracks than if you’d tried making an all-rounder car, but so what? Finishing 14/15 is worth the same points as 19/20. Doing the the extreme low drag approach at least puts you in contention for points at tracks like Monza and those handfuls of points can be huge for a team at the bottom of the standings.
