Yeah, smart. They would probably have lost anyway, and they would have had to spend effort and money on it which maybe could divert them from racing or developing their car.
Rosberg needs to get his shit together if he's going to win the WDC and I honestly believe that he probably isn't capable of stepping up another gear. Hamilton can be erratic and can swing in performance but his highs are higher than Rosberg's.
Regarding the Silverstone race, I was sad to see McLaren out of the points and I didn't like seeing Verstappen beating Ricciardo. Come on, Danny.
