#4 The Renaults crash into each other
Renault had a very strange race in Bahrain that did not end well for them. After Daniel Ricciardo was put on an odd 1 stop strategy opposing the rest of the grid, he and Nico Hulkenberg actually managed to put their cars in the points and were running well.
Even after a little bit of a touch earlier when Ricciardo locked up into turn 1, both Renaults managed to keep going and looked to finish with some good points.
However, with a few laps to go, both Renaults incurred mechanical failures and that too, seemingly two different problems. All of Ricciardo's electric cut out, while Hulkenberg seemingly had an engine blowout.
Even in Australia Renault had some bad luck, while Hulkenberg finished P7, Ricciardo had an unfortunate wing loss and retirement in his home race.
I don't see Renault's bad luck going away in China and with both Hulkenberg and Ricciardo looking to be keen put in a good performance I see him running into each other at some point to bring out a safety car.
Whether it will be a case of fair racing gone a tad wrong, or another lockup like in Bahrain that isn't saved by a few inches, but I see the bumblebee patterned Renaults picking up a Double DNF and setting up an incident to put some spice into the race in China.
