Uhh, no, ships in space do not have a speed limit, it is completely impossible for them to have one because there is no friction in space. You apply thrust, it goes faster. Ships in cutscenes and animations have been seen going much, much faster than in gameplay. "Max velocity" is a gameplay contrivance that has no relation to the way actual space travel works. And if you're not going to attempt to reconcile the subject of a debate with actual real-life mechanics, there's no point arguing about anything because you can answer any question with "a wizard did it'.
A ship in space cannot have its speed limited by anything but fuel supply, space just doesn't work that way. Furthermore, speed is relative, so a ship traveling at 55 m/s relative to one planet might be moving 100,000 m/s relative to a star a few light-years away, which means that aside from being impossible, max speed doesn't even mean anything in space anyway because speed is entirely dependent on the observer.
