1) Wheels look to narrow for the weight. They would leave ruts all over the course.
2) Battery looks too small for the weight. They wouldn’t run long enough.
3) No spot to sit down. One of the virtues of a regular golf cart.
4) Only carries one. A typical golf cart carries a party of 4. So you need four of these or one golf cart.
5) No shade. Typical golf cart provides a spot of shade also. Great for a kid or wife tagging along.
Now if you changed the rules to allow hitting from one of these... at speed, then you might have something.
Horseless Polo, anyone?
