It's rare for cyclists to speed on roads.   Most people can't pedal faster than about 30 kph.   No cyclist takes pleasure in narrowly missing anyone.   The consequences for the cyclist of hitting anything are just as or even more dire than for the object or person being hit - the cyclist will get thrown, lose some skin, maybe break a bone and/or damage bike.   If you think anyone is deriving pleasure from narrowly missing other human beings, you're probably projecting your own driving experience.
