I think the lack of wider acceptance is multifaceted... the difficulty of retrofit being one factor. I think probably for some the road vehicles on their layouts are more part of the scenery which, whilst you want to look good, you don’t want to distract from your trains which are the “actors” of the layout. And there are of course other options for moving cars though I do tend to think EZ Streets is the simplest of the lot. I do wonder also if people were more aware of the predecessor SuperStreets and were just unaware that Bachman picked up production after K Line was fully subsumed by Lionel?
I do think that EZ Streets is kind of ideal for adding a trolley line to layouts or building a traction layout and I do wonder if more people have tried that. I know Lee was also toying with the idea of using it for street running which I think would be a spectacular addition to layouts large and small.
