I know it’s difficult and there is no perfect answer or simple pill that will cure all. Rules is good, but only if the other person flying the kite or in the buggy knows about them.
I think it’s up to us who can and are to educate those who want to and will be. Numerous times I have been on Gwithian, Cornwall with 15+ buggies, and boarders, static flyers etc all doing their thing.
It only takes 10 minutes time out to help someone who is new to it, and if we all spend 10 minutes each time we are out helping the new guys and gals then calm will overcome rant.
I know it can be frustrating at times and some kid goes out and buys a big kite, gets dragged all over the hard sand are with buggies racing, but in general most people respond well to help and advice, and sometimes that’s all it takes.
Remember, we all had start once….
Just my 2p’s worth
