FIA explain 'unprecedented' glitch that caused Bahrain GP start chaos

The FIA revealed an “unprecedented” glitch caused several cars to stop in the chaotic start to the Bahrain Grand Prix in Malaysia.

Heavy rain in Sepang caused a delayed start but when the drivers left the pit lane, multiple drivers almost grinded to a halt including race leader Max Verstappen and Ferrari's Lewis Hamilton with several drivers in the midfield also experiencing issues.
