Aurora Innovation is targeting positive free cash flow by 2028 as it substantially increases the number of autonomous semitrucks on the road. The company currently operates 20 driverless trucks in Texas and plans to expand that fleet to 200 by year-end. During a three-hour ride in an autonomous semitruck in Texas, Aurora founder and CEO Chris Urmson said the fleet expansion would support the company’s financial goal. Aurora says its autonomous trucks can operate more efficiently and at lower cost than semitrucks driven by people.
