A Beep shuttle bus on San Francisco's Treasure Island
The bus is made by Beep, whose vehicles are also used in Yellowstone National Park.
  • A driverless bus will run a seven-stop loop around Treasure Island in San Francisco Bay.
  • It can seat up to 10 passengers and will complete the loop every 20 minutes. 
  • San Francisco authorities last week allowed driverless taxis to operate 24 hours a day.

Just a week after allowing robotaxis to operate around the clock, San Francisco has launched an driverless shuttle bus service.

The small box-shaped bus will operate on a fixed route on Treasure Island in San Francisco Bay between 9 a.m. and 6 p.m. to serve its 2,000 residents.

While it has no steering wheel or driver's seat, an attendant will always be on board. The electric vehicle was built by Florida-based Beep, which provides similar transport in Yellowstone National Park and Miami Zoo.
