Only if you push it. On a perfectly flat surface, in neutral it will not roll without assistance.
If it's parked on a flat it should not roll at all
you are a cone
yes
So it doesn't roll off when you place it on a flat surface.
A face.
A smooth and flat surface with minimal friction, such as a polished marble floor, will allow a ball to roll the fastest. The lack of friction will reduce resistance and enable the ball to maintain its speed for longer distances.
The object described is a cone. A cone has one vertex (the point where the flat face meets the curved surface) and one flat face (the circular base). Due to its shape, a cone can roll along a flat surface smoothly.
Put it in neutral and push it.
either the e-brake did not release or it is still in gear
A ball can roll faster on a flat surface compared to a bumpy surface because the flat surface provides less resistance and allows for smoother motion. On a bumpy surface, the irregularities create friction and obstacles that slow the ball down. Additionally, the energy lost in bouncing over bumps further reduces its speed. Thus, a flat surface generally facilitates faster rolling.
A cone fits the description.
Most likely a bad brake calpier.
