The problem is that uber doesn't investigate DUIs.
The cab company...
Twice i've been ordered off the road to wait for The company insurance/safety guy to show up and breathalyze me and once they just called the sheriff's on suspicion that i was DUI. ( i suspect it's because the company guy couldn't make it quick enough)
They ordered me to pull over on the spot. I *ALMOST* comply with it and go to a parking lot cause that's a MUCH nicer place to be stuck waiting than roadside. I'm 100% sure that this is because of liability issues of suspecting a driver is DUI.
There are am stuck in some crappy 711 telling people who walk up looking for a ride that i broke down and am waiting for a tow (seemed like a better idea than telling them the truth)
All three times i was investigated and all three times i was only off the road for a period of less than an hour.
That's how you investigate these accusations. On the spot when the customer calls it in. With just sending emails you will never get the truth. You need someone who is neither the driver nor the passenger to make them blow into a breathalyzer unit and make them walk a line.
On top of that the issue is resolved much faster than the same situation with Scruber and Gryft.
The cab company refunded me rental time for the time i was off the road for my troubles. Which I personally think is going above and beyond..
