The asteroid belt in our own solar system was of concern with early unmanned probes until it’s actual composition was better known.

No giant slugs of course.“You’re not actually going into an asteroid field,” “Sir, the possibility of successfully navigating an asteroid field is approximately 3,720 to 1,” the implication in both being that going through any asteroid field is incredibly dangerous.
Look, I don’t care if in reality some asteroid fields are dangerous or not. Doesn’t matter to me, and it doesn’t matter to the movies I watch, clearly. That’s the point. In Star Wars, they don’t do a scan or some shit of this particular asteroid field to see how dangerous it is, they just barge right in, with it being dangerous as a given. Even Threepio’s numbers are just complete random bullshit, done to establish the threat in a way that’s true to his character (and, of course, Han’s).
And how many times do they do the exact same thing in Star Trek?
Again, you’re looking at it the wrong way. Saying they do the same thing in Star Trek doesn’t say anything but about Star Trek. Han and Leia fall in love in Empire Strikes Back, many characters fall in love in Gone with the Wind, does that mean that Star Wars is actually a period romance?
