I live in SF, and was flying out of OAK. I had used Uber only once before, a long time ago; but this time, I suggested to the wife that we use Uber again. We had to leave SF at 7:15AM - 7:30AM or so.
Around 7:15 I pulled up the app, and saw that there were several cars around (as they usually are). I requested an UberX; punched in the destination. A driver quickly accepted, and Uber said he'd be there in < 5 minutes. A couple of minutes later, I get the notification that the driver cancelled. OK, I tried again. Same thing again: driver accepts, and then a minute or two later, cancels. This went on for 4-5 times. Now, time is getting tighter, and I have a large suitcase; and cabs don't come around in my alley. I tried Uber again, and this time Uber says: "Surge pricing in effect! Rates are 1.5X". I knew what was going on; but I had to accept out of desperation. What do you know? A driver quickly came over and we were on our way. The driver did say that some drivers may not have wanted to go to OAK because traffic back would have been bad.
But here's the thing: a licensed cab cannot refuse to take you to your destination! Uber seems to be set up to take advantage of riders with their "surge pricing" scam.
This experience left a bitter taste in my mouth, and I made sure I installed Lyft for the ride back.
