Yeah, I can see that. If it were as easy as I initially thought it would be, then the taxi companies would have apps as good as Uber's. It's hard for me to understand why the existing taxi companies are so slow to adopt the best parts of Uber's business.
I've used Uber quite a bit and even if it were the same price or slightly more expensive than a regular cab, I would still use it because (so far) my Uber experiences have been much better than any taxi experience. I just wish Uber would either pay the drivers more or let me tip through the app.
