I use to say that in some airports , and in airports you have never been before , it`s more dificult to taxi than flying around.
yes true, thats why you have absolute discretion to decide when and if the First Officer gets to do the driving ( both on the ground and in the Air )
If you think that it is marginal ( crosswind, contaminated, mechanical failure, congested busy ramp, One Engine taxi etc etc etc... ) then you'd better take over.
That's what you are paid to decide.
