thats the usual thing they do--flash their lights and speed up! i dont understand why most of them are so arrogant and impatient when to think they impose speed limits...whats it for? just numbers? if we ignore them--they'll overtake and make a sudden brake...and then for sure when accidents happen -- its us whose at fault. well--this isnt our territory and what else can we do but give way??? thats the best thing to do...cheers!
