There were no injuries reported, and the shuttle didn't suffer any major damage, according to a report by a local Fox news station. Nevertheless, Las Vegas city representatives seem happy at the result - none of the passengers was injured and the shuttle apparently performed as it was created to. The shuttle's sensors identified the truck and the threat of an accident and stopped, but the delivery truck did not and grazed the shuttle's fender.
"We were all like, 'h my gosh, he's going to hit us, he's going to hit us, ' and then, BAM", said Jenny Wong, passenger on shuttle! "Unfortunately the human element, the driver of the truck, didn't stop".
The truck driver was cited by authorities over the accident, the city said.
The driver of the lorry which crashed with the bus was subsequently given a ticket.
Shortly after the shuttle began running, it was involved in a minor accident when a delivery truck backed into it, grazing the shuttle's front tires.More news: Putin and Trump will Meet Tomorrow

According to the BBC, the bus - the first of its kind to carry passengers in the U.S. - was travelling at a low speed in Las Vegas when it collided with a lorry.
The self-driving bus, developed by Navya, does not have brake pedals or a steering wheel.
Maurice Bell, vice president of Mobility Solutions for Keolis Transit America, said the shuttle would continue to operate after undergoing a complete diagnostics assessment.
The shuttle is sponsored by AAA Northern California, Nevada and Utah, and in a year-long pilot project is expected to ferry 250,000 people at a top speed of 15 miles per hour.
The shuttle, which is being run through a partnership of vehicle company Navya and transportation firm Keolis, had already been through a successful controlled trial in Vegas.
