Lewis Hamilton's crucial missed pit-stop in the closing stages of the Saudi Arabian Grand Prix came about due to a confusing situation on track, Mercedes boss Toto Wolff said.
Hamilton was seemingly presented a golden opportunity to stop on Lap 37 under a Virtual Safety Car, which results in a much smaller net loss than stopping under normal race conditions.
Doing so would have capped Hamilton's recovery drive from 15th on the grid with a decent points haul, but he finished 10th, scoring just a solitary championship point.
The VSC was prompted by a bizarre sequence of events as Fernando Alonso and Daniel Ricciardo both encountered car trouble in the final part of the lap and stopped their cars on the approach to the pit entry.
