Maximum torque and maximum efficiency are not the same with electric motors. As you point out, maximum torque is at stall, which is completely inefficient. A non-spinning motor at maximum torque is doing no work because horsepower is calculated by (torque * RPM) / 5252. The result of zero RPM is zero HP.
I'm not clear what the most efficient RPM and torque % would be on an electric motor, but it's a way more linear relationship than with petrol engines. Auto manufacturers would certainly attempt to keep them in optimal operating ranges.
MODs- This should probably live in General Efficiency discussion or Fossil Fuel Free
