Well, I enjoy asteroids the same way I enjoy holes in a jump and run: by successfully avoiding them. Or, occasionally, shaking off enemies by making them avoid the hits.
I think it's really good that your fleet interacts with the terrain, it makes both feel more substantial.
I don't have a problem with the player fleet having terrain interactions; I
do have a problem with holding down 's' the whole time I'm in Magec or Isirah or crossing a wide patch of hyperstorms or whatever when I don't want to turn off the transponder and thus don't want to run dark - especially because it's significantly more convenient to make temporary course changes by left-clicking in the main game screen than by opening the map up and right-clicking, but even tapping 's' while flying a course set by left-clicking in the main screen causes the fleet to come to a stop.
Also, what's the use-case for "standard burn" speed? It's too fast for hazard avoidance, it's significantly less stealthy but (especially with the Sensors skill) little faster than darkened running (and if you're actually running a stealth fleet, that becomes even worse, because it's entirely possible to have fleets that have sensor profiles of only like 150 or 200 with Sustained Burn active, especially if you're willing to spend story points and built-in hullmod slots on Insulated Engine Assemblies for at least your big ships and thus have battleships with the nominal sensor profile of a phase frigate), it's too much slower than Sustained Burn for regular travel when you don't care about stealth, and it's not actually much if any better for hunting other fleets than any other speed because it gives any fleet that's afraid of you too much time to react whereas coming in hot and fast on Emergency or Sustained Burn can often catch a fleet before it decides to bolt (and even if you don't catch them before they bolt, Emergency/Sustained Burn can also let you run down pretty much anything given time even if you for some reason haven't put Augmented Engines on that battleship or don't have Bulk Transport boosting those Atlases you're dragging along or haven't included tugs in your fleet) while Going Dark, especially with some phase ships in the fleet, can let you creep up almost right on top of the target before it sees you coming.
