I agree. I'm not saying this didn't happen; we don't know, but there's a lot fishy about this story when you account for the author's prior history.
First, there's the laundry list of excuses that leads to her just HAVING to use Uber (train gap was too long, nothing to read, screaming guy, competing app just wouldn't fucking work no matter how hard she tried... fuck it, I'll use Uber). Why does she have to work so hard to justify using Uber? The most likely explanation seems to be because she's got a massive track-record of writing pieces dragging Uber through the dirt. If she really hates and mistrusts Uber that much, why not just call a Yellowcab by standard telephone call or something? They still have those, you know...
Then there's the whole way this event plays out after the driver first calls. It's not impossible, but it reads like it's out of an injustice fanfic post or something. Driver gets irrationally angry at her not being where she should be where driver is in the wrong, she cancels, then boom, another call, instant rape threats with the driver rolling up, making it clear that he can see her. And her commentary on it is... she will never forgive herself for not having a snappier comeback, but hey, she was tired?! I don't know how they do things in San Fran, but around these parts if I'm alone and unarmed at a bus/train station that already feels a bit sketch and the only other person there, rolling up in a vehicle, no less, drops an angry rape threat on me, I'm not going to be coming up with a "snappy comeback." ALL the alarm bells should be going off by then.
Then driver rolls across at closer proximity (increasing threat level), and NOW the shit's getting real? And she'll ring doorbells if it gets more nuts?! And then we get the death threat. She says she's calling the police. And the driver just... hangs around after dropping all manner of illegal threats because he doesn't think she canceled the trip? I mean... it's possible that he's just totally unhinged, doesn't think he can get caught, or has no idea as to the gravity of what he did, but that doesn't make a whit of sense.
Then there's the voicemail, which, as others here noticed, doesn't really sound angry at all. It sounds extremely frustrated, but that's about it. Now, he could have cleaned up his act thinking that a voicemail would be permanent but a call wouldn't, but this just doesn't sound like someone who was screaming death threats a minute ago. And once again, his primary concern seems to be that she cancel the trip, which is odd unless he just doesn't even know that dropping death threats and rape threats is a really big deal.
And then there's the police response which, if the story was delivered straight, is just fucking baffling. First, the author is wrong: in addition to a headshot and first name, the Uber app gives the make of the vehicle and, critically, the license plate number. That's about as close to positive vehicle ID as you can get, and they have the telephone number too.
The cops asked all the right questions, fine, but they didn't do anything? I would hope that they would put out a B.O.L.O. on the car and at least try to pull him over to see if he's high or deranged, if not just get that cab off the road before the driver gets to play Fuck Ferry Kill with the next lucky fare.
Once again, I'm not saying none of this happened. It's possible that this driver was just totally off the handle and lost his shit. It's possible that, because he's foreign, he doesn't understand the weight attached to death threats and rape threats in most parts of the world, or in the moment didn't care. But the story is weird as fuck, the article author's reactions are weirder, and the cop's reactions is even stranger than that (unless they just weren't taking this seriously, which I would expect they should have because of the INCREDIBLE amount of shit they and their department would have been shoveled if they took it easy and the cabbie hurt someone else later that night). Coupled with the author's writing history, I'm skeptical.
