1. Don't see the point of economic class vs first class pods when the whole point is to get you to your destination so fast you won't be in the pod for very long. Mid-class pods for all makes more sense.
2. Please don't emulate the airport model and build over priced malls within a "security zone". A Hyperloop is supposed to get you from point A to point B quickly. Following the airport model will add two hours to every trip.
