Hmm... well, I wouldn't quite go that far. Maybe "focused", but not really "ignorant", and certainly not "arrogant".

For my purposes, in my area, I can think of maybe two kinds of bicycle that would work great -- one would be a folder, the other would be a step-through "girl's" frame. Both would have dynohubs & lights, internal gearing, fenders, a rack or two, and an upright stance with either traditional "North Road" bars or narrow flat bars.

That's pretty much it. Many other flavors of bike would have advantages that don't mean much in this particular setting, and disadvantages that would make them less desirable than the two bikes I just outlined.
