Tires are new and properly inflated. On level ground, I can push the car with two fingers, so I'd like to think that the brakes are not dragging. Also up on jack stands, all 4 wheels spin easily.
And I just had the front end aligned a few days before I did the first measured mileage test, so that should be spot on.
I know that the 11" motor is a lot of motor for a 1900 lb car, but I was initially thinking about putting a WarP 13" in it!. For a Cobra, there is no such thing as overkill! Too much power is not quite enough!!
When driving at a steady 50 mph versus a steady 40 mph on a level road, I see a significant increase in motor current. So in my humble estimation it is mostly air resistance that I'm fighting.

An open-top roadster is horrible for aerodynamics, the rollbar probably makes it even worse, and that big grill opening..
If you get this even at 50mph might have some type of drag going on.
Check the brakes. Check motor for drag.
With fat tires be sure alignment is correct, fully inflate the tires.
There has been a big trend to get a "big block" e-motor to go fast.
An 11" motor is overkill for such a light car.
