Uber is not the only game in town, people still got Taxis before uber.

Not true. From USA Today:
In the second quarter of 2015, 31% of ground transportation receipts were from Uber, 24% from taxis, and 45% from rental cars.

Last year at the same time, Uber accounted for 8% of receipts, taxis 37% and rental cars 55%.

If you take rental cars out of the equation, Uber made up 55% of receipts vs. 43% for taxis in Q2 2015. Lyft and other rideshare services accounted for the rest of the expenses

And that is "receipts," not number of rides. Since Uber is generally half or more cheaper than a taxi, that means that FAR more people are using Uber than traditional taxis

I think the thing that people are forgetting is that surges are based on supply and demand. I've never been at TIA and didn't see the full allotment of drivers available on the rider app. Since TIA is a place that drivers automatically flock to, there is always a glut of drivers there, thus supply always outpaces demand, thus no surge. I believe it IS possible for there to be a surge at TIA, there just hasn't been the correct set of circumstances yet for it to happen.
