Did you think Airbus' Pop.Up flying taxi concept was a little drab? So did Audi. It teamed up with Airbus and Italdesign to unveil Pop.Up Next, a reworked version of the two-seat autonomous vehicle concept. The new version is more stylish than the mostly functional original, and borrows more than a few cues from Audi's current design language. However, it should also be more practical -- it's supposed to be "significantly" lighter than the original, which is rather important for a hybrid passenger drone.
