PITTSBURGH (AP) — Autonomous truck company Aurora Innovation says it won't start hauling freight without humans on board until April of next year, a delay from previous statements that commercial service would begin by the end of 2024. The Pittsburgh company on Wednesday said the April launch of driverless semis traveling from Dallas to Houston will be “modestly later” than the company had intended. The company told investors on its third-quarter earnings conference call that it has made progress toward ensuring its trucks will operate safely.
