I understand your concern and it is valid, because as it stands there are plenty of ways to get around the heath inspection issue. However I suspect that this model will take off and the delivery apps will start to address your concerns. The southwest model (ever minute the plane isn't flying were loosing money) applies to kitchen space as well. Depending on your locale there is a lot of it out there being underutilized. Lots of places require that food trucks have (and many need) a physical location. Having that be in an out of the way place and NOT having to a retail side is a massive savings as the location can be "shared" and potentially come at a massive savings. Leveraging these same places for delivery only businesses (or in the case of one local truck a delivery option near the kitchen they use) has been a boon to all involved.
