Are you sure that you were in the right and there were two left turn lanes? There is an intersection by me that everyone uses wrong and you get folks using it as a double turn lane when the lanes have text that say the name of the road you are technically supposed to stay on. Really the city is to blame and not the driver because it’s confusing but still, I think the lanes are all mapped manually for Waymo (but personally I don’t have any inside knowledge)

Traveling south here on Land Park Dr there are two lanes, some people from the right lane veer left and the left lane veer right through the middle of the intersection. There aren’t dotted lines to help.

Quite certain. The two left lanes can both turn left, and the middle lane can also go straight. It's well marked (though a bit tight if you try to take it fast).

Is the turn you're referring to the one where lane 1 (the inner left) then merges into lane 2 after the receiving block segment starts? (John Daly Blvd. onto Park Plaza Dr. southbound)

I wonder how something like that is represented to the waymo or reasoned about.
