That is understandably going to make public transport a lot less desirable to you. What goes on in your local public transport is probably not quite universal about public transport, though. So, as I said, it makes sense as a weighing factor -- and in this case it sounds like a significant one for your individual preferences -- but it doesn't mean the suggested hierarchy doesn't make sense in other ways if you don't have that factor. And if looking at it from a general community structure or transport infrastructure planning point of view, those probably shouldn't be based on the assumption that public transport means having to deal with dicks.
