Many US airport ground frequencies would get IMMEDIATELY overloaded if ground controller started giving out the endless conditional sequential taxi clearances during a normal, or heavy, traffic period.
Yeah, it works when there's hardly any traffic - "oh this works great! Why don't they do that in XYZ airport in the U.S.?" Add U.S. level of airport movement and it falls apart.
The difference in workload in the U.S. ATC system vs. the 'busy' European cities is almost night and day. A 'busy' period overseas is an easy day at work for U.S. based pilots. I can't pretend to know all the how's and why's but the operational pace is much easier overseas. Not saying the U.S. is perfect and the 'end all to be all'. Could it be fixed? I don't know.
Overseas they expect you to have read all the written procedures(P pages). The U.S. expects you to listen up to what guys ahead of you are getting and what you get assigned. Identifying flights ahead of you, and the clearances they get, helps you increase your situational awareness. Just sitting there as a sponge, without increasing your traffic situational awareness via TCAS and radio monitoring of what other flights are being assigned, isn't a good idea in the U.S.
