Today's Brazilian GP. At the start Ricciardo charges into T1 like a wild man, come down the hill out of control, runs off the track and pulls back on squeezing Vandoorne into Magnussen taking both of them out. Ricciardo continues. No action, no penalty. Same lap, 4 turns later, Ocon takes a risk on the outside of Grosjean in the fast, tricky T6. Grosjean's car pushes the front end and collides with Ocon's racecar. Both leave the tack to the outside of the turn. Ocon is out for the day, Grosjean continues, safely re-entering the track. Grosjean gets a 10 second penalty. I know officiating is not easy, not exact sometimes. But this seems wrong to me. Any thoughts?
