It depends what you're talking about the speed of. The speed of an electrical signal in a conductor might be fairly independent of current, but I was thinking in terms of the average bulk velocity of electrons, which is directly proportional to the current (with the constant of proportionality being the conduction electron density).
I suppose how you think of it depends on what you're interested in. The Rev as an electrician cares about the macroscopic behaviour of circuits, I as a physicist think in terms of the microscopics.

So no..this example is an accurate, yet simple analogy.
Oh, the heat of the water is an analogy for Ohmic dissipation. Now I understand!
