I missed it."When your life is saved nobody owes you anything. I don't hold any rancour towards the sport. The only thing I want is for the safety in races and tests to be improved."I will collaborate with them on what is currently lacking. Moreover, I feel very grateful to all the teams and drivers who have supported me after the accident."She is currently working with the International Automobile Federation to help increase the prominence of female drivers in motorsport.
