That's only safe if there are a reasonable number of lanes, namely no more than 2. Beyond that the width is higher, the possibility of a car far away blocking the view of another car slightly behind increases and the driving speed of the cars is increased because it feels safe enough for them. And from what I've seen in the West Coast, narrow human-sized roads are reserved exclusively for back alleys.
