Uber's Flying Cars, Tesla's Troubles, and More Car News This Week

Transportation is a world full of visionaries: big ideas gone even bigger. It attracts world shakers (and breakers) like Grimes' Boyfriend, Travis Kalanick, and Mark Moore, a 30-year NASA veteran who decamped last year for Uber's new flying car project. There are lots of fanciful renderings and prototypes, lots of pulled-off covers and pointing of spotlights. Plans that run out of money, petering out and puttering toward death. Cars that crash and kill. Which is all to say: It was a mixed bag of a week.
