One particular instance of this I pay attention to is the placement of oil filters on motorcycles. My brother bought a Honda CBR600RR, and he wanted to replace the oil filter; I watched him spend an inordinate amount of time removing the cowling, clip by clip, screw by screw, from the bike, in order to expose the filter (which you could not get a normal filter wrench onto, because of the awkward positioning).

After that I pay a lot of attention to whether the oil filter is visible and accessible from the outside of the bike without removing a cowling, Kawasaki seems to do a good job of this.

Yup. Previous incarnation of a VW Golf had an engine compartment that fit together, and you could replace the headlight bulb in about 20 minutes with common tools. Current one has an engine compartment that fits together, and you can't replace the very same bulb unless you take half of the damn thing apart, and then you hit a snag, because the very last screw is unaccessible unless you're a nanobot, has a special nut, and some sort of seal guarding it. I suppose it does make sense if you have the whole workshop at your disposal and can disassemble and reassemble entire vehicles at will.
