I agree with Hikermor -- whatever you think of the story (or stories) surrounding it, the bus is now a historical artifact with cultural significance. The story and its mythology, as they say, have "legs." Somehow this resonates deeply with people.

The bus (and famous suitcase) just need to be displayed in a suitable shrine where pilgrim travellers can "touch the bones" and have their moment of epiphany without putting themselves and first responders at unnecessary risk.
