Gave up?! I cannot imagine how anyone has thought that over the last 2 years. Mercedes obviously earnestly searched/pondered/researched every inch of their car to try to figure it out. Look how much Russell was able to do with the flawed design! So much so they stuck with it for another half year. When you wrote your post, they were already talking about the redesign.
The redesign is proof of their hard work. Their previous UFO design never made sense to me. Too much spill over. Admittedly, my aero training is from Bill Stine's book.

Happy to see the talented Lewis smile today!
I've been watching F1 since 2000. The sport is moving in a great direction. I'm always cheering for the under dog. Max is amazing talent.
Alonso is awesome although I wonder if Stroll's team is keeping up with the upgrades.
Wish Haas could do better. Their chassis scrubs the tires too much.
Ferrari, oh my goodness! They lose so much with dimwitted strategy. Sainz deserves better!
