So in All Live this question was actually asked and the answer was basically that it is because of shortage of kilometers in the car. As Hyundai is a bit different he hasn't learned all the tricks. Probably also what is the best setup for him in this car. I think with more km's, more understanding, setting the car up like he wants, learning the tricks and also development, he should be fine in couple of rallies. Hopefully it is not late then.
