Interesting that the shark just chills there. Still lots of controversies about the "rough shark" theory and whether to hunt it down.
Statistics wise, the obvious has been stated time and time again..
If you are not scared of driving or suffocating whilst eating, it's highly irrational to get excited about sharks, especially whilst kiting.
That said, exceptions do exist, e.g. the South-East coast of Florida at certain times when hundreds of them pass close to shore. It still comes down to individual risk assessment, but personally I would neither dive with sharks, nor kite with shaky legs because I'm surrounded by them.
