Agree with other posters. See too many golf cart driver overly cautious and/or afraid of executing that move. I used both a mechanical and hand signal and merge with auto vehicle traffic.
the concern for golf cart drivers is the occasional car that insists no golf cart will move in front of them.

conversely, an automobile should not get in the habit of crossing the solid white line that defines the diamond lane. yet I see many cars execute a right turn utilizing the diamond lane. One of these days they are going to hurt someone because the golf cart will be in their blind spot. Safe driving means safe habits and safe habits means constant practice.
