But let's be serious for a moment and consider already valid points made by Syrus, and build on them.
Short summary:
Freelancer is not to scale.
Freelancer is also not the most realistic.
Basically, if Freelancer was to scale, those planets you see, the bases, and the stars, would be some tens, hundreds, or maybe even a thousand times bigger, and to the same effect, apart from each other.
Trade lanes wouldn't be the length of a few 10k from one end to the other, they would have to be some million kilometres between each point of interest (probably a LOT more trafficked, too, but at the same time less noticable because of the scale)
These things considered we still have:
The law of conservation.
Energy requirements.
Just the same as you have the ability to thrust, you need the ability to not spiral out of control.
The law of relativity.
Basically, if you have something that big, even in the vacuum of space, the faster such a thing goes, the harder it is to turn it. Believe me, I've done my astrophysics homework.
If your own arguments are to be taken seriously, the fact that your ship moves that fast means that it would take just as much just to SLOW DOWN, and then even more to turn it. Therefore having more speed on a large, cumbersome ship (by this I mean it's a long/wide/whatever ship, so turning it is gonna take a while, for obvious reasons) just makes it even less agile.
It's a concept that works with most vehicles, space or not.
The faster it goes in one direction, the less -likely- is it that it will turn on a dime. Especially when speeding.
So aside from how ridiculous your arguments end up being..
Am I supposed to advocate we get maps that are so large that traders will never be truly safe and distances will be boring to cover due to scale?
No.
Edit:
Tl;dr it kinda just sounds like you want a cure-all for your own hubris.
Go fly a bomber. Should solve your problem.
Would also give me something to kill with my LF or VHF
Dat's rite, flying LFs like a boss.
