OBVIOUSLY, you could have solved the problem with motor braking. The driver is not going to accept fault until there is conclusive evidence of the their wrongdoing, but you can't let the team know you are going to repeat the test again but with a different driver because then they will invent objections to pushing the car up the hill.

Turn the car around 180 degrees facing up. Coast down the hill in reverse and control your descent with the throttle.
