Waymo, the autonomous vehicle company under Alphabet, has started creating 3D maps in some heavily trafficked sections of Los Angeles to better understand congestion there and determine if its self-driving vehicles would be a good fit in the city.

For now, Waymo is bringing just three of its self-driving Chrysler Pacifica minivans to Los Angeles to map downtown and a section of Wilshire Boulevard known as Miracle Mile.
