Unless you're at a section of MM path that is divided, there is usually no need for a bicyclist to move over to allow a golf cart to pass. Assuming that there are no vehicles coming the the opposite direction, the cart simply moves into the left hand lane. I've seen a problem when there are multiple cyclist riding together in a group and they don't ride single file. As I said I came across this once and every time I went to pass several of them would move out to the left to prevent me from passing. They were traveling at around 13-15 mph but they refused to let me pass.
There was also an area that I used to travel quite frequently where a group of bicyclist would often be stopped for a rest. The problem was that some of them had a section of their bikes still on the cart path. This particular spot was on a pretty severe curve and you really couldn't well in front of you.
I don't think that all bicyclists are arrogant but certainly some are. Some of those that are serious riders seem to feel that they are superior to the rest of us. Or, they seem to feel that they have a right to be doing whatever it is they're doing. It's too bad because that kind of attitude is going to get someone seriously injured or killed some day. I've seen the same attitude with people that walk on the paths. I ride my bike every day and I try to use common sense. That's all that is really required to keep everyone safe.
The Florida law states that if someone is trying to pass you on a four lane road, you must move over to the right hand lane to allow them to pass. This applies regardless of your speed or their speed. It also states that a vehicle is not allowed to impede another vehicle that is attempting to pass. Now this law applies to motor vehicles, but I would assume that it also might apply to bicycles.
The reason that these laws have been passed is that it has been shown that impeding a vehicle that is trying to pass causes more accidents than does speeding.
