The possible outcome may have been,
Cyclist gets swept into the sea, someone on the passing trains see it happen, they dial 999, police, coastguard and probably fire service attend, all 3 services risk their lives look for a plonker, what a waste of time and resources, unfortunately things like this happen all to often.
DW I assume this was on your local news? if that's the case I only hope they mentioned how stupid the cyclist was.
