[Warhammer 40k]. What are cars like in the Warhammer universe?

Good question, the answer is that just about every form of personal vehicular transportation is available in the Imperium; access to these vehicles depend on your class in the Imperium's byzantine hierarchy.

Personal transportation can range from the elegant grav-cars of Terran nobility to ramshackle trucks that would not look out of place in the 21st millennium. 

Personal transportation is not limited to terrestrial traffic either, Inquisitor Eisenhorn owns a gun-cutter, which is capable of void travel as well as flying within the atmosphere of a planet.
