Stuck on three
There's one more reason why it might prove tricky to travel the spaceways at relativistic speeds. As spaceships approach the speed of light, or so this paper claims, interstellar hydrogen turns into intense radiation that fries the electronics in a spacecraft and kills everyone inside. The easy way to get round this is to go slower, but that kind of defeats the object of travelling at close-to-light speeds in the first place.
