Elbert - you are mostly right - but until something official is done I'm afraid citizens will continue to take things into their own hands. Speeding is a BIG issue. I agree we don't have speedometers on our golf carts but the cars, motorcycles, taxis and trucks do. AND - even in a golf cart you know when someone is doing excessive speed.
Instead of arguing minutia here lets get together and demand at the very least basic traffic control.
