IIRC, in Star Trek, they’re not even supposed to go beyond light speed in the Solar System. It’d be like trying to drive 100 mph in Midtown Manhattan: You’re going to crash into something.
My point for years - ever since Star Trek.......at that speed, there would be no way to avoid a random asteroid, planet - or even a star.....it would be suicidal.
It is inconceivable that any automated guidance system could be devised to steer around objects at that speed. In fact, a course adjustment required to do so might just kill everyone in the ship due to momental inertia.
But then - it was once inconceivable that man could fly, or go to the moon...........
