Spooky,
I go in and out of LAX all the time, but we do things differently there anyway, don't we? Not a lot of places as busy where we can't read anything back but our callsign and transponder code. And of course most of the equipment there should be landed on the centerline.
Last night I rode as a passenger on a B737. On arrival, taxiing to the gate, the airplane jolted, and at first I tought we ran over a large set of chocks. I glanced out the window, and half the winglet was gone. When I exited at the terminal, the airplane we hit had pulled into the adjacent gate. Our winglet was sticking out of his horizontal stab. It happens. Infrequently, but it happens. Big or small.
I believe the other 737, same company, has been taxiing for departure. From my vantage point as a half-awake passenger, I couldn't tell if we were on the centerline or where the aircraft were positioned relative to eath other. When we were taxiing in, the thought did occur to me that due to the number and proximity of other aircraft, I'd be taxiing slower if it were me, but didn't think much about it. The aircraft was about to start a right turn into the gate when the left wing impacted the right horizontal stab of the other aircraft. How exactly that happened I'm not sure...I'm not even sure who hit whom.
I've known two folks who hit things with the wing of a C-130. I've watched people hit other aircraft objects, a flag pole, a cafe, a fuel truck, a large powdered bale of retardant, a car, and a host of other things with wingtips and even propellers. All sorts of stupid pilot tricks, all unintentional, pretty much all by experienced pilots or crews.
Working with students, I strive hard for, and insist on using the centerline. Working in a professional certificate environment, moving paying passengers, I try hard for the centerline, and insist on it from my first officer. In large aircraft, I use the centerline for taxi, takeoff, and landing where possible.
In other operations and when necessary, I use what I need, when I need it. That includes taxiways for takeoff and landing on occasion, even the odd closed runway (once this summer) when it's been warranted. So the same with highways, roads, and so forth. I also follow the glideslope or glidepath where it's availble, but won't hesitate to use all the runway starting at the numbers or before where appropriate, either.
