“What? Would I do a ridiculous amount of relativistic math to calculate our relative velocity at any given moment as perceived by my inertial reference frame and then do Lorentz transformations to figure out when the light from his engines will drop out of the Petrovascope’s perception range? Just so I know how much longer I can see my friend in the distance? Wouldn’t that be kind of pathetic? Yeah.”
