What is your response when a car passes you (illegally) when you are already exceeding posted speed limits?

My gripe comes from a rash of recent incidents where I have been passed (occasionally honked at) while taking the road when travelling at 45 to 60 kph. Most of the time in areas of corners or double lines. The last truck passed when I was travelling 7 kph over the PSL. It is as if they "need to pass" the bicycle.
