I suppose the general idea is that objects tend to give us info about the spacetime along a line tangent to their worldline. (Or just along their worldlines, if we have enough information to predict those. And ofc, one fundamental asymmetry is that dx/dt <= c, but dt/dx can be as high as we like.)

Things with high dx/dt give us info 'sideways' in the physical world. (Someone threw a ball at me, so I know what happened very recently off to the left.) Things with high dt/dx give us info going forward in time. (My desk isn't moving right now, so it will probably be here for the next hour.)

Hadn't thought about that before - this is a really interesting asymmetry to consider! I'd tend to interpret it as a statement that there are a lot of stationary or slow-moving objects in our lives.
