Just to clarify an issue, let me state that golf carts are NOT a problem.
If someone drives into this bunker, any other bunker on the golf course, or the front gates, they're either impaired vis a vis drugs and/or alcohol, or have fallen asleep at the wheel.
THE issue is, ELIMINATING buffers of rough that act as a safety net to slow down and prevent balls from entering a bunker.
OFTEN, it's NOT a maintainance issue, but, a cultural issue.
