This has no provision for slow walkers. Cart GPS is irrelevant to them. GPS in carts with your position on the display is a good feature, but it's really ony effect when carts are required.
This attitude is nothing more that sticking your head in the sand. You're saying that since you can't see an obvious cure, there isn't one so just ignore it. If more people are told by their buddies that they are slow, they might start to believe it and do something about it. But someone they trust needs to tell them, because most of them aren't even aware that they are the problem - even now many aren't even aware that there is a problem. And that is really where the problem lies.
There are a dozen little ways for most players to improve their pace of play, but if they don't know they have a problem they aren't going to seek a solution.
I tried telling a friend once. It was in-between holes. I told him we were falling behind and that we had to start playing "ready golf" and "cut down on the excess practices" swings. Of course, his next shot was horrible & he blamed me for rushing him. We were a two-some and were falling behind a foursome. I haven't played with him in 2-3 years.
Another buddy I have plays really slow too. I have mentioned it to him away from the golf course, but it never seems to do any good.
Maybe you have had better luck with your playing partners, but I have not. Also, if there was an "obvious cure" someone would fix the problem.
