Re:
You have to define 'road bike'.. To me, 'road bike' is a distinct category from 'roadster' or 'tourer'. It implies something lightweight that was designed to cruise at 25mph, burdened only by the rider, which in turn implies an upper body position optimised for cutting down wind-resistance rather than one optimised for admiring the scenery.
With that in mind, these kind of bikes look 'right' when the stem is lower than the saddle. Imo it doesn't matter much whether the bars are flat or drops.
For contrast.. we have all(?) seen a photo of a nice old Colnago or something, probably not serviced since 1978 when it was last raced, with the seat post slammed down as far as it will go under a comfy padded saddle, the stem raised as far as it will go, the (drop) bars angled back as far as they will go, and a shopping basket on the front.
That is how you negate the aesthetics of a road bike, but it makes practical sense if you retired from racing in 1978 and were left with a Colnago. Why buy another bike just to go shopping?
