Doesn't answer the OP's question but the mini bus drivers are absolutely speed freaks. On the bus route I use sometimes, the drivers take curves as if the bus is a race car. Then drafting passenger cars around turns and on the straightaway all for no reason other than their own adrenaline rush. Almost always these guys are exceeding the speed limit and don't even care its flashing on the screen to passengers.The bus leans so much on turns and at such high speed you feel as it it will just rollover IMO.
