TuSimple says its self-driving trucks shaved 10 hours off a 24-hour run

Autonomous vehicle company TuSimple on Wednesday claimed that its trucks shaved 10 hours off what's normally a 24-hour job. The company tested its trucks by hauling fresh watermelons along a 951-mile route from Nogales, Arizona to Oklahoma City. The run normally takes 24 hours and 6 minutes with human drivers and traditional trucks, but TuSimple's automated driving systems enabled a 42% faster run of 14 hours and six minutes, the company said. According to TuSimple, a human driver worked on the pick-up and delivery of the produce. But during the long middle segment of the drive -- from Tucson, Arizona, to Dallas, Texas -- TuSimple's vehicle drove itself with a human safety driver on board.
