I'm a little confused how a team pulling a reel at the parkbench would cause all that much trouble. You can always run a line on the righthand side of the parkbench to get around them. The team behind you in the cornflakes could have taken a shortcut on the left to get past everything, but that way only works if you aren't carrying stages or scooters and you aren't too fat.

I have only a few times been annoyed at divers in devil's getting in my way. But, I know the cave there pretty well, and it's usually not an issue to slip around someone. Usually, I dive at night to avoid the traffic, because it can get ridiculous during the day.
