We figured this entire movie out from beginning to end in the very first scene of the movie. My roommate called out everything that was going to happen right before it happened.
The real moral of the story in this movie is: don't just hop into cars assuming they're your uber while completely ignoring your uber driver....and if you get a call from somebody saying "hey. This is your uber driver. I'm here. Where are you?", they are more likely to be your actual uber driver than you already being in an uber. There is no mistake on their end, but rather yours.
Also, why would you uber black in an suv for one person? Uberx it. Save money.
