In Indonesia, the DGAC report to the Ministry of Transport.
By encouraging massive expansion of LCC, they have saved tens of thousands of lives. Lion Air, Air Asia et al have taken people off ferries and overnight busses that have a much much worse safety record.
In an ideal world, yes, the busses and ferries should be better regulated. But at least the Indonesian LCC have to at least try and meet ICAO standards - a bus crash in Sumatra would never get investigated.
