Would a low battery still let it roll on the ground? Or no?
with the power you had in the video, it should rolled. perhaps not as in the end, but earlier.
If wheel are "stuck", normally it would tipped over(or tried to) though.
In my testings of a plane, i take it out the lawn, at a place with medium height grass, Can it move, superb , if stuck, just tipping forward/rearward, i know forward moving power is ok, just not correct surface for the plane. Our airfield is quite nice cutted low, or i can also easy take out the lawnmover tractor, and cut it even more. Or even roll out a length of plasticgrass. who is superb for any plane/small wheels)
On asphalt every plane with wheels should roll easy. Dont need full power either
