Well, Yes. Basically a skinny cart. When I proposed these to course owner a good quality model was $1,700. They have Yamahas. The best, IMO. The math worked. And, the range of them was waaaay more than twice that of a 2 passenger. Number of charging stations and overall real estate for same would/could be an issue.
Number of wheels on the course is a valid concern. I think the weight of singles would somewhat offset that concern.
Often, we have a 90 degree restriction. You know, stay in the rough until you’re even with your shot. Then go straight out and straight back to the cart path. Can’t tell you how often that is ignored. Plus, people unnecessarily driving through low, wet, areas. Grrrrr!
