People in LA wait to jaywalk on the street or even in the suicide lane all the time. The Waymos handle it fine; generally by asserting it has right of way unless collision is obviously imminent. They'll even happily swerve around you if you're too far out.

What is a "suicide lane"?

A single middle lane shared by both directions for left turns. Also unofficially used as parking for food/package delivery drivers in LA.

Shared turning lane.

Pedestrians always have the right of way on city streets. Jaywalking is just walking.

No, you cannot just step in front of a moving car such that they cannot stop.

This is what they tell you in driver's education to try and reduce the odds you hit pedestrians, but it's not legally true in most jurisdictions.
