Then later (I think on Jan 2nd?) they updated their blog post, presumably in response to details of the driver being released, to confirm that the driver was an Uber driver (just not one on an active trip), and that he has been deactivated.
Then it closes by repeating the condolences to the family.
I agree that it would have been nice if Uber could have confirmed that the driver worked for them initially, but it's not obvious that they were even in a position to find that out before details on the driver were released.
If a Yellow Cab driver killed someone do you think they would deny, admit and then caveat with 'but he doesnt really work for us because he didnt have a passenger in the car and his lunch break was coming up blah blah blah'
Yes, if a yellow cab driver hit someone with his own car while he was not working (which is what happened here), yellow cab would very much deny any liability.
At first Uber denied the driver worked for them. Then they admitted the driver was with them but he wasn't "working" because he didn't have a passenger.
In constrast, some news reports claim that the driver believes he was working for Uber because he was searching for fares at the time of the accident.
They were more worried about being associated with the accident than the accident itself. Lots of weasel words and excuses in trying to claim that the driver didn't work for them, or that the driver wasn't active or doing a trip.
If I worked for Uber, I would have posted something simple and left it at that e.g.
"We have been informed by law enforcement that there has been a traffic accident in San Francisco involving an Uber driver. We send our deepest condolences to the family and victims of this tragic accident."
The end.
Of course they care more about being associated with this particular incident than about the singular victim.
Are you going to call them out for not expressing condolences for the other hundred people that died to cars that day?
To my reading, it sounds like they simply had no way of knowing that the driver worked for them without the police giving them details on the driver.
