You can have as many clues as you like, but there will always be a way of circumventing them. Someone mentioned the SQ6 incident at TPE. Those guys knew LWMO were in force and hard tuned the ILS to get the PVD working. But when they lined up on the taxiway and one of the crew pointed out that the PVD was spinning, indicating that they were way off the runway centreline, the Captain chose to ignore it.
In the HKA incident, it occurred in an area of the airport which is not normally used by departing aircraft and looks different to the other thresholds. The fact that this type of incident has occured more than once from this point indicates that something needs to be done here. Such as a big "TAXIWAY" note painted on taxiway 'A'. Pilots don't like being treated like idiots, but it seems that in some cases it's justified!
