I remember when my aunt got her ankle broken when she was a passenger in a crash because she had her legs up on the air bag. Fortunately, Momoka doesn't have to worry about that; she isn't wearing a seat belt, so she would just die in a crash.
^And the Goddess of Yuri is protecting her! Madoka will save her one way or another. And we probably shouldn't operate under the assumption Nina is definitely gonna crash lol
