I knew a person, will not say the name to protect the innocent, so this person, who should remain nameless, got their hand stuck in the "black hole" so badly the seat had to be unbolted and removed. Sigh, by the fire department. You see, the person really did try to pull the hand free, but the hand was not coming free. So when there was a mention of blood and at a public rest stop, well the fire department was called. Not by the person that got their hand stuck. The person was trying to explain that the fire department was unnecessary, if only someone would go into the trunk, get the tools out of it, and unbolt the seat. Nope fire departments. Lights and everything.
5 minutes later, hand was free, blood soaked carpet, and one dislocated digit, but self respect was never found. This was almost 20 years ago, and the person that shall remain nameless, still has scars from it.
NEVER CHASE ANYTHING INTO THE GAP.
