MLG teleport clutch.

Could just also use it to travel any speed too if it stops velocity

You could put on an astronauts suit and warp across space

Ammm, that proves that you'll likely end up in the door. If you stand facing the door and measure 7 inches from the back of the foot towards the door, you likely won't pass the door.

If a door is 2 inches thick and thickest part of your body is the length of your foot in inches, let's say 11 inches which Google tells me is a reasonable length for a man's foot, then to travel far enough into the direction of the door so that the back of your foot ends up on the other side of the door, you'd need to travel 11+2 inches.

Depends on how it's measured. I was supposing a position at the center of your mass being used, but there are no guidelines to go by. Guess you just have to take the pill and see how it works! Personally, I'd pick something else unless I had a way to verify how it worked beforehand.

Must be difficult to eat!

You can do this already without the pill, you are just limited to objects that are somewhat sharp.

Ba baaaaa bababadabada
