I reckon overtaking cyclists fast is fine, the only things you want to overtake slowly is horses, I think cyclists are aware what a car is and (within reason obviously) getting past them quickly (within a speed safe for the road/situation) means less time spent alongside, which is the dangerous bit. The same way you stick your foot down if you are overtaking a car. I get annoyed when people overtake me at about 1mph faster than I'm going because if something unforeseen happens on the other side of the road, their first reaction will be to avoid it and take me out ib the process.
