Able-bodied people using Buggies in competitions. Golf can be knackering in the heat we've had this weekend, especially if you're playing consecutive days or multiple rounds in one day. Being able to use a buggy clearly offers a physical advantage which the majority of the field (at least in the UK) wont have.
I am afraid that you have drifted into 'use of technology' territory with this ... and like DMDs you will find little sympathy.
My simple answer to the 'unfairness use of a buggy gives in this weather' complaint is that if you can afford to play golf you can afford to hire a buggy for a couple of days. Besides you can have a caddy to carry you clubs or drive/push/pull your bag trolley to reduce physical exertion.
