They seem to have found some way to create the rear wing end plate, which the rule definitely did not intend to.   One of the fundamental purpose of an end plate is to increase wing's efficiency by limiting the spill flow and reducing the wingtip vortex. This indeed could be a very powerful device for downforce gaining, drag management, etc. The article below is the wingtip part of the 2022 Formula 1 technical regulation with my comments comparing it with the Aston Martin wing tip. Note that I'm just a university student, not a professional engineer, so there can be some mistake. All the pictures below were made or edited by me. The red letters below are my comments checking its legality....

This is nonacademic post containing my own guesses for F1 aerodynamic elements. Again, this is nonacademic post not including scientific proof. I'm just doing this for future reference like a diary.
