Sounds reasonable, but compare with a 12V car rated at 30A. How do we manage to 
rate several 16A fuses? I guess it's implicit in here that you should not 
expect to use the max current from all of these for extended periods at the 
same time.

FWIW, whenever I've measured the current drawn by any of my normal loads I get 
numbers that are well below the fuse ratings. The FI fuel pump, for example, 
gets a 16A fuse, but almost never draws more than 4A. Russ's example of a 
windshield wiper frozen to the windshield is just about the only example I can 
think of where you could have a large current without a short in the system 
somewhere.
