What’s the point of Seaford’s HGV car park?

Can anyone tell me why, next to the Buckle car park, there is an HGV one, right on the seafront?

Having never seen an HGV in there let alone at the weekends, it seems a waste of good much needed space for cars, given the current fine weather.

Do not try to park there even if empty. You will be ticketed by the traffic gestapo as well as on the seafront if not between lines. Welcome to Sunny Seaford!
