Oh it does, easily - You don't have to tell the driver where you're going, you don't have to pay the driver, you don't even tip the driver. It's all handled by the app.
Agree with you.
Security ? - No need to carry cash or even a payment card on you. When I researched the number of taxi driver incidents earlier this year following my uber thread, the information I found suggested uber drivers were only a minority of known bad drivers in the UK. You and the driver are both tracked by GPS as well. Plus the uber system logs who is the driver and passenger for each and every journey, this makes it harder for a driver to do something and get away with it, so actively discourages bad behaviour.
Reliability - Not sure what he meant by this, but if he means drivers honouring jobs, then I can only really compare uber to my previous taxi service of which uber is more reliable.
Service - not much to say really, you dont have to stand out in the street hailing cabs, dont need to ring someone up, dont need cash lying around to pay driver, dont need to prebook in advance even at peak hours, its a on demand taxi service to pick up from your current location, booked online with fully automated payments. I had one bad experience a few weeks back where a driver cancelled my pickup and the new driver would have been late so I cancelled the new driver, I was then charged as if I had originally cancelled it, I went on the app and said he cancelled it and was instantly refunded.
If black cabs work the same way as yellow cabs in new york and black cabs in Leicester then they are a limited service, you need to find one to use it, In Leicester they parked in the city centre (special privileges) and outside the train station, but otherwise you never ever see one, so if you not in one of those 2 places you not even getting one. The atmosphere in the vehicle whenever I have used one is sour, you on the backseat behind a metal grating like police cars have, driver doesnt talk, no radio etc. They deliberately go to traffic jams when they exist so they can charge more on the meter as well I feel, so there is that distrust between the driver and passenger.
So you can see there is an argument for the other side as well as to why uber is superior, and many people in the UK do agree with me, hence the situation we have in london with black cabbies trying to get the competition banned as they unwilling to adapt to more modern practices.
If somehow the uber ban goes through, something will replace uber, the monopoly the black cabs have enjoyed is coming to and end I am afraid stuart.
