What is difficult about taxying an aircraft?? I'm amazed what strange variations there are in the airline world. Surely if you can't be trusted to taxi, you shouldn't be flying the thing! (obviously helps if you have a RHS tiller! All my companies fleet were so fitted)
A good Captain should delegate as much of the decision making/operation as possible, on their F/O handling sectors. You are of course, as Captain, the final arbiter.
