So what would it mean to have 3.2 million such establishments on our streets? Well, according to an article at something called "FoodBeast," there are already 3 million food trucks in America, so apparently we wouldn't really notice them. Unless that figure is wrong. For example: "According to TruckInfo there are about 15 million trucks on the road in the U.S. This means 1 in 5 trucks on the road are food trucks." Which seems high.
