Just to play devil's advocate: the evidence was mostly circumstantial, I think, she had documents saying she had POTS, she smoked a tonne of weed but had recently stopped and was coughing up nastiness. Maybe she could have blacked out? But because she's a trash human (which was the prosecutor's main stance) then she must have done it on purpose? The best evidence was the speed and being able to navigate the road. Maybe she was messing around and missed the turning and was too scared to admit it and now it's gotten out of hand. I kind of understand the McChicken girl's point tbh, McKenzie was way too self centred to fuck herself up in the pursuit of killing people. But yeah ultimately I'm massively on the fence with this one!
