I'm not denying that it's thrilling, but that doesn't mean it shouldn't be done responsibly. Racing cars is thrilling, but that doesn't mean you should be allowed to do it on public roads. And they do put peoples lives in danger when they get near the beaches and islands. They have little regard for other users of the water.

btw, they can and do impose restrictions on the water. They are not allowed by the Corniche or the hotel beaches, but unsurprisingly this is ignored.
