If I read it right, the EM drive could continuously propel a vehicle forward. Okay, build up speed with a drive that provides constant acceleration. So. What about slowing down? They still have to do with mass and velocity and what it is going to take to not splatter on the moon.
I’d suggest the flight drive curve would look like a narrow bell curve with the second half “propelling in the reverse direction”. Hardly a ‘warp’ drive.
You can use it for artificial gravity. 1 g to halfway. Turn around and 1 g till you land. You can up it to 2 Gs if your in a hurry and strapped in
Also think of the G forces while accelerating. The craft would have to limit its acceleration or people in the craft be a Flat Stanley.
That would slow the trip down
