@nunatak There are over 20 million kilometres of roads in the world. If you estimate an average of 4 intersections per km, that is 80 million intersections. Figure each intersection has four corners, so that's 320 million corners. If there's a taco truck on every corner, and a taco truck can serve 200 meals, that's 64 billion meals. So the answer is obvious: TACO TRUCKS ON EVERY CORNER!
