The accident panel recommended the implementation of a "virtual safety car", based on the "slow zone" system used in Le Mans racing. Compared to the former, the safety car does not actually appear on the track. On top of not being allowed to overtake under yellow flag conditions in the affected sector, a "VSC" icon would appear trackside and on the drivers' steering displays, obliging drivers to not exceed the posted speed limit, thus resulting in a 35% speed reduction. The system was similar to the Electro-PACER lights used in the Indianapolis 500 races from 1972 until 1978, except that engine control units (ECU) were involved and could enforce speed limits under the current system. The VSC was tested over the course of the final three races of the season, during parts of free practice sessions. The system was evolved taking into account drivers' feedback and was officially introduced for the season following ratification by the World Motor Sport Council (WMSC). The VSC was officially used for the first time, and for a brief period prior to the deployment of the actual safety car, at the 2015 Monaco Grand Prix, following a 30G crash involving Max Verstappen. The system saw its first extended deployment at the 2015 British Grand Prix after Carlos Sainz Jr.'s power unit failed at Club Corner of the Silverstone Circuit. All drivers must keep their delta times positive at this point. Formula E The Full Course Yellow condition is the Formula E version of the Virtual Safety Car. In this condition, all marshal posts will wave yellow flags, accompanied by a sign that says "FCY" with a yellow background. This condition is often decided by the Race Director whether it is
