Don't Panic (Hitch Hiker's Guide...)

[Kamog]

There were three types of engines: hyper drive, improbability drive, and bistromathic drive. I think the improbability drive allows your ship to pass through all points of the universe in an instant. The bistromathic drive is more advanced, and you need a bistro, a little restaurant, inside your ship.

Also, there's the Somebody Else's Problem field (SEP) which is like a cloaking device. It doesn't turn your ship invisible, but causes people to ignore it because it becomes somebody else's problem.
