I was able to do sone off road training with the daughter of one of the top racer/engineers.
She thanked me for not being stupid after our training. She told me of the stupid thing other have done. It is not so much trust but as a student showing respect to the teacher.
If you show respect and humility toward the teacher you will lear more and gain their trust. I have found once they trust you they will work extra to get more out of you because they do not fear you over stepping things.
Same when I did some testing in a stock car. I was chose by the owner as in his words said I want you to drive because I know you won’t do anything stupid. He is the one who taught me to not try to be a hero to save a spin. He said turn in and just spin to the infield. You can get back on the track then. If you try to be a hero you will hit the wall. I never had to spin but he later had a guy who was a hero and knocked the back clip off the car.
