A Las Vegas autonomous bus started service — and crashed an hour later.

The driverless bus was hit by a delivery truck that the bus company claims "didn't yield." The shuttle stopped like it was supposed to, with little damage and no injuries.

The AAA and Keolis shuttle bus had a two-week trial earlier this year and will now serve three stops in Downtown Las Vegas on a 12-month trial basis. Let's hope this is just a slight bump in the road.
