A childhood belief about cars

I was told by some neighbor's kids that there was a hole under the driver's seat of my dad's truck and in the hole there was a huge floating fire and then if you went through the fire you would fall onto the road and die instantly. I started crying when they stuffed my teddy bear under the seat and I tried to save him but was afraid to die. Luckily, my dad found out a couple hours later and told me they were kidding.
