F1 undertook another mixed opening day of action, following the drama that hit Las Vegas GP FP1 and FP2, with the first session at the Yas Marina circuit effectively a mini rookie test with 10 new drivers in action.
After that, second practice was truncated heavily by two red-flag stoppages; the first for a heavy crash by Carlos Sainz that required barrier repairs before another crash for Nico Hulkenberg.
