I need more power Cap'n!
I disagree with the statement that there is no reason to have multiple motors if you have a shifter.
They cover similar problems, but not EXACTLY the same problems. If you need or want more power (e.g. for faster accelerations) multiple motors gives you that. Notice that I use the term "power" in the engineering sense. I do NOT mean "more low end torque" as many do when they use the term on these fori. POWER = WORK PER SECOND <-- SPEED X TORQUE in our case. Switching gear ratios can help you get more power up to a point by choosing to load the motor such that it is providing its peak power (i.e. at 1/2 its stall torque) but if you need or want more power than that, more motors are your only real solution.
