'Confused' Waymo self-driving cars are flooding a dead-end street in San Francisco

Residents of what is typically a quiet neighborhood in San Francisco are being plagued with humming from several Waymo vehicles crowding a dead-end street. The mysterious sightings are coming from the end of 15th Avenue, where up to 50 of the self-driving cars appear to be confused as they enter the area, residents told local news station KPIX. Resident Jennifer King told KPIX that the vehicles, which are being tested in the California city, all make a multi-point turn and then just leaving from where they came in – and sometimes multiple cars arrive at once. 'I noticed it while I was sleeping,' Jennifer King, a resident in Richmond District told KPIX. 'I awoke to a strange hum and I thought there was a spacecraft outside my bedroom window.'
