Uber also displays the license plate number of the car and the vehicle make/model in the app when you make your order. This provides an additional level of verification if you have security concerns.
Faking Uber would be easier. Admittedly, iirc, these people were scammed relatively easily and at less of a threshold than pretending to be an Uber drive would require.
Interesting, maybe it isn't that far-fetched after all, though the risks of doing this by impersonating an Uber driver seem a little too hight to convince scammers.
Actually, its not really a solution. All of these identifiers are easily duplicated :/
