The logistics of food is endlessly interesting when you step outside the reach of the robotic hands of supermarket distribution. Along with the produce, transport is what adds a degree of regional variation to most markets. One of my most enduring memories of one market in Cambodia is seeing a Toyota Camry, whose backseat had been hastily waterproofed with plastic tarpaulins, filled to the ceiling with live snakehead fish.
There are certainly more preferable ways to transport food, but there is no perfect means to transport food, which is why the humble cargo bike (below) can continue to compete with every other vehicle on Penang to transport eggs.
Whenever I see a bike like that, I just want to follow it.
