It's also pretty fascinating to look at the Satellite images. Here you can check out the latest from the hi-res GOES-16. It's insane to see the scale of the hurricane, all told.
It's not just the TSA that will make this popular - I see the convenience as a big draw. As this expands to more regional airports, it will be even more practical. Being able to drive to a smaller, less crowded airport will be a selling point. You don't have to deal with the stresses of huge terminals and tons of people.
