On Thursday night, Elon Musk rolled out Tesla‘s biggest gizmo yet: a fully electric semitruck. The Semi can go a whopping 500 miles between charges, hauling 80,000 pounds along the way. And it can sorta, kinda drive itself—on highways, anyway. The truck comes with Enhanced Autopilot, the second generation of Tesla’s semiautonomous technology, equipped with automatic braking, lane keeping, and lane departure warnings.
“Every truck we sell has Autopilot as standard,” Musk said of the Semi, which goes into production in 2019. “This is a massive increase in safety.”
That may be true—about 4,000 Americans die in truck-related collisions every year, and human error is responsible for many of them. Self-driving trucks will certainly change lives. That goes double for the nearly 3.2 million people currently employed as delivery and heavy truck drivers. But we don’t know how – no one really knows.
