Out here in the void everything spins around at who knows how many times the speed of light but for practical purposes speed is measured according to nearby stations and ships. I often find myself zooming past targets because my HUD does not give me this information; if my target is moving towards me at 150 units then I don't want to zoom past him at 350 and knowing my target's speed would help greatly

The computer pilots have this information, why do I not have it
