Elon Musk crashed his own party at Tesla's Semi event with a surprise staged to the Beastie Boys banger: Tesla's making a brand-new Roadster. Arriving in 2020, and, Tesla CEO Elon Musk said, designed to “give a hardcore smack-down to gasoline cars,” the new all-electric Roadster will have world-record-beating specs. It was Musk's first "one more thing moment," former Apple CEO Steve Jobs' famous mantra that made Apple's hardware reveal events such electrifying events.
