I liked UberX while I was in the city. Awesome ridesharing. Great.

I don't understand why Uber, in a regulated taxi eco system like London or Berlin, wouldn't just start with UberTAXI? Why not start the process gently by being able to hail a cab and pay through the app. This is the most problematic issue for me as a user. Getting a dedicated cab to show up to my location, just for me.

While living in the Bay Area, I talked to several (yellow) cab drivers that love Uber because it guarantees a fair that their dispatch service can't.

Why does Uber not enter new markets by making booking Taxis easier first, then introduce X at a later point when their brand is better known in a new market?
