Doha: Jules Bianchi was driving too fast when he spun out of control and crashed at the Japanese Grand Prix, an FIA report into the accident published on Wednesday suggests.

The Marussia driver collided with a recovery vehicle on lap 43 of the rain-drenched Suzuka track on October 5.
One of the conclusions of the 10-man FIA review panel's 356-page report was that "Bianchi did not slow sufficiently to avoid losing control at the same point on the track as Sutil".
The report found that a series of key incidents likely contributed to Bianchi hitting a mobile crane that was removing Adrian Sutil's stricken Sauber car at the time at 126kmph.
These included: surface water reducing the racing line at Turn 7; the process of removing Sutil's car; Bianchi's speed and over-steering.
After being brought out of an artificial coma Bianchi arrived back in France last month, and is being treated at a hospital in Nice.
His condition was described as "critical but stable" in the last medical update. The report also stated that "if drivers adhere to the requirements of double yellow flags...then neither competitors nor officials should be put in immediate or physical danger".
