> According to the article this was a 4 lane road, and she was in the furthest lane to the left of the Uber driver.
No, she was turning left from a perpendicular street, from the leftmost lane in her original direction of travel into the rightmost lane in the new direction of travel. Pop
> The Uber driver was in furthest right lane, with a left turn signal on, preparing to change lanes.
The last part is a disputed claim, per the article.
> So, she cut across two lanes to crash into oncoming traffic
I'm not sure how you figure that; she ran into crossing (not oncoming) traffic, and I don't see any way of counting where it works out to cutting across two lanes.
> I'm not sure of the Pittsburgh driving laws, but generally you're supposed to get into your left-most lane before taking a left.
She was making a left turn from the leftmost lane; that's not in dispute.
> I don't think she has a hope in court
I don't either, but that's because making a car making a left into crossing traffic, unless the crossing traffic is violating a control (stop sign, signal, etc.) or speeding, is almost always at fault because of right-of-way
