I was waiting in line at the airport recently, thinking about my Escatak concept--an idea to combine check-in, security, and customs in one escalator ride. And I figured: Why wait until you reach the airport to get that process started? Sure, you can check-in remotely and get your boarding pass on your phone, but you still have to wait in line to register and check your luggage. So I've drummed up the Nexus, an autonomous minivan concept that carries you to the airport, and on the way gets you fully ready for your flight. This self-driving van would carry a modified luggage trunk that would weigh, measure, and inspect each bag with an x-ray and chemical analysis, in conjunction with airport security.
