They’re called “multi-modal paths”, open to pedestrians, bikes, and golf carts. Rules for their use? Don’t hit anyone or anything and don’t get hit yourself.

Whatever you do or whatever happens, stay polite and calm. Others you may encounter may not act accordingly. Remember, it takes two to tango!

I ride many enjoyable miles each week on my road bike. I use the MMP and find them smooth and safe compared to the roads themselves.
It is wise to ride defensively and keep your attention from wandering. I have had a few unpleasant near misses with a distracted golf cart driver.
Even so, I have enjoyed getting off busy roads of my last city and onto relatively less busy and safer MMP.

Same here.

just be a defensive rider....and expect that the other fellow doesn't see you
