What I expected to happen was the endermite would get caught in the minecart when it ran into the minecart.

What actually happened was it phased right through the minecart and at one point the minecart actually sat on top of the endermite.

Steps to reproduce.
1. Spawn an endermite in the end
2. Have the endermite move or fall on top of the minecart, or have the minecart roll on top of the endermite.
3.
