Waymo robotaxis have made their standby parking lot into a honking mess

• Waymo robotaxis wait in a rented San Francisco parking lot overnight when no riders are around.
• NBC Bay Area first reported the autonomous cars sometimes honk for over an hour while they park.
• The honking, which occurs as early as 4 a.m., is part of a known issue the company is addressing.

Waymo robotaxis are waking their San Francisco neighbors with a cacophony of overnight honking as the autonomous cars navigate the parking lot where they idle waiting for new riders.
