F1's much anticipated romp around the streets of Vegas hit an early roadblock when the cars of Carlos Sainz and Esteban Ocon dislodged water valve covers, which damaged both of their chassis beyond repair and led to FP1 being abandoned after eight minutes.
After emergency fixes were applied to the 30 similar covers around the 6.2km street circuit, FP2 eventually shifted to 2:30am local time from its original midnight slot.
