Max Verstappen gave a damning verdict of the Japanese Grand Prix stewards after his retirement -- "I really don't understand what's going on with the rules today".
Verstappen was knocked out of contention for a strong result on the exit of Turn 1, when Charles Leclerc drifted into his car. That pitched Verstappen into a spin and left him with car damage which ultimately led to his retirement mid-way through the race.
The incident was not initially investigated, which prompted a censored radio message from Verstappen, before the stewards decided to look into it after the race.
