WILLOWS, Calif. — Sometimes progress comes as two steps forward and one step back. But sometimes it comes with one full step backward.
Or more precisely, one full lap backward.
An engineering team from startup Point One Navigation accomplished that feat in autonomous mode on a blustery morning last week, sending its Lexus CT 200h in reverse around a 2-mile track at Thunderhill Raceway Park in Northern California at an event called Self Racing Cars. Then they did it again.
