Good race. It's annoying me that the penalties don't carry any more, though. Hamilton took a ridiculous 55 place drop, but this wasn't actually reflected in his starting position, and he got massive advantages for the race with new power components (upgrades), not having to bother about qualifying - so no stress on the power unit and loads of tyres left over, and a perfect, race focussed setup. Because it doesn't matter once you've hit the back of the grid it doesn't matter, the teams took a raft of extra power components to give him additional choices later in the season, defeating the point of having penalties for changing components in the first place.
Not that I like seeing drivers demoted for changing engines anyway, but I find the whole thing ludicrous. The situation was the same with Alonso, who took a 30 place penalty., But only actually lost two places.
Then we have red flag situations. Now, like back in Monaco, teams are allowed to change the cars however they see fit during the red flag stoppage period, which effectively destroyed the dramatic end of the race because nobody was struggling for tyres any more. Fair enough, fix things that are broken, or making the car unsafe, but changing strategy or setup should not be permitted. Essentially put the race on pause.
