It doesn't matter how fast you are going really. It's all about how you are affecting others.
Of course -- and my response was really tongue in cheek. But, in general, there are fewer boaters to deal with up there, of course...
Truth is, I've lost two complete rigs (rod, reel and all) this season alone from such boaters zooming in behind me while I was trolling. The most recent one cost me about $200, too!

I also think that there are truly people that do not realize, either at that moment or ever, that you have a long fishing line out of the back of your boat that they could run over. There have been times that I just stand up waving and pointing behind me and then they get the picture in the nick of time.
Just imagine what our roads would be like if there were no white lines or separators and we all were just trying to get where we need to go. The bottom line to me is the more people around, the more bad apples around.
