There's already a powered minecart that runs on coal, you can use a glitch to make minecarts go really fast, and they're adding a single block which will do the same thing in the next patch anyway.
As for my ideas, I think there should be a mob which can slowly destroy blocks, and a mob which poisons you, meaning that you have to run back to the surface in order to survive.
Most minecraft suggestions seem to be way over the top. There was a serious suggestion I saw on the forums for the height limit to be increased to 20000 blocks...
