Could be any number on things on the taxi. Checklists, verifying final load data, mx issues that pop up at the last second, FAs still giving their safety briefings. I know I've had to adjust my taxi speed to accomodate all that and probably some other things I'm forgetting.
Yeah, I hate it when guys taxi fast. I have a lot of stuff to do between beginning to taxi and getting to the end of the runway. I'm pretty convinced that something is going to go wrong some day when one of our f/o's is heads down starting an engine while one of our old farts scoots across an active.
