IMO if your poor vehicle driver usually means your poor golf car driver.
I also think the problem too many carts governors have been tamper with even on LSV. I have clocked to many exceeding well and over 30 MPH.
IMO there will always be another golf car accident, just like there will always be another vehicle accident. To seat belt golf carts or not? Damned it you do and damned it you don't? Just depends on the situation you get into. I personally like and have seat belts and my cart IAW the law. When I am driving along in my golf cart I am in the defensive mood. Just like when I ride bike. I assume the car will pull out in front of me, cut me off, and basically ignore me, so I already off the gas and ready to break or swerve to negate getting hit.
