It isn't the number of hubs, it's the amount of traffic on the segment
(and the number of hosts creating that traffic).  As that rises, so do
the number of collisions till a point is reached where devices spend
more time backing off and retransmitting than they do transmitting data.
This puts a practical upper limit on the capacity of an ethernet network
that is significantly below its theoretical maximum.

There's also a maximum length to an ethernet segment.  Maybe some wise
soul can give a url to some stats, I'm going from memory.
