Please let it come to Beijing
I know it would never be allowed, but it would be wonderful if Uber, and similar facilities, were allowed in Beijing. At the moment, we have: (a) droves of taxis that become unavailable all at the same time, because drivers share one taxi, and they all handover at the same time, (b) taxi drivers who have little or no training, so they don't know how to drive to quite famous landmarks, and don't want to be shown, either, (c) taxi drivers who just say "I don't want to go there", either because it's too far, or they don't make enough money from the trip, (d) taxi drivers who try to find out who you are so they can calculate if they can go on a "scenic route" to charge you lots of extra money, (e) taxi drivers who just refuse to take foreigners and pretend to not see you unless you stand in front of them when they are driving down the road, (f) taxi drivers to agree to take you, then decide they can't and ask you to get out but still charge you the minimum price, and (g) whole areas where you just cannot find a taxi, and they are as rare as hens' teeth. I know places far from a metro station where you have to walk for more than 20 minutes before you have a chance to hail a taxi, and they seem to have no concept of taxi ranks in Beijing except at stations and airports. If you want to complain about some taxis, the authorities say there are safeguards, but it isn't easy to get the information the authorities require to take action, and you're not sure if they even do take action in many cases. So, something like Uber would be a godsend.
