Yes, because the pedestrian slowed down when it saw the Tesla was not giving them right of way (as the Tesla is required to in the state of california).

> In my state that's perfectly legal.

In most states its illegal to force a vehicle or pedestrian or whatever that has right of way to slow to a near stop to avoid a collision with you that you could have easily stopped and avoided. I don't know of a state where a pedestrian in a crosswalk would not have right of way in this situation.

Now, there are many states where a pedestrian in a crosswalk doesn't have like right of way over everything (though, technically, not california), but for the most part this applies to vehicles that could cross the crosswalk without affecting the pedestrian.
