I live in a golf retirement community in Arizona.  Sun City, Sun City West, Sun City Grand.  Golf carts both gas and electric share the road with full size cars and trucks.  Maximum speed limit within the community is 35 mph and the carts have lights, turn signals, horn and seat belts and a speed limiter of 25 mph.  Gas carts get 40 mph with a 5 or 6 gallon tank, electric carts get about 35 mp charge, insurance can be added at the back end of your car insurance for less than $50.  This saves quite a bit on car maintenance and costs.  The community has everything you need except big box stores which are close but not accessible by golf cart.  I'm not familiar with other 55 plus communities in Arizona that allow golf carts.
