The star rating don't really mean much. It's more of a popularity contest. However being forced to adhere to the same regulations as taxis is a very good thing. I do wish that happened here. If it did, I'd re-evaluate my stand on uber as that's the one thing I am pushing for here, that uber...
As an idea Uber is fine. I liek the concept.
In practice however Uber does not have the same protections for the drivers and customers that proper taxi companies do. Also there's less checks made for drivers wanting to run their own uber.
A google search didn't take me long to find this...
