So you're basically saying that since it's a compressor motor, it can't be run at a variable speed?
Keep in mind, that I (once again) would be using it in a vehicle whose
total weight is less than or at 1,000 lbs, not counting myself. Wherever you're coming up with your weight figures, it's obviously not from reading my posts.
The 100% duty cycle of the motor means that it
can be run at max output 100% of the time, not that it can't be run at variable speed. What do you think a VSC does? The motors in that link aren't just compressor motors, either.

Table saws, conveyors, augers, fans, and many pieces of D&P equip run at variable speeds, using a VSC. Sure, none of those things just give the motor open contact and expect it to accelerate under load, but aside from overheating (which can be taken care of), what problem would it really be?
I do, however, know that I can't actually use those motors that I had linked. They're inductive motors, and I won't be able to get enough starting torque to move them without a complex, inefficient circuit.
Regardless of that point, the original question was whether a 5HP motor would be sufficient to move a small (</= 1000#) vehicle at city speeds, at or near 25MPH, on flat roads. That question has been answered. The answer is Yes.
