That's not it - I've taken UberX here about 15 or so times - and the drivers have all been courteous, professional and timely. A lot of them are black car drivers as well, so it's hit and miss when you summon an UberX vehicle, you might just end up with a Lexus a professional driver.
When I see where the cars are, and where I am, I can usually make a guess as to how long they will be based on a months worth of local knowledge - another example is traffic flows to/from Sharjah, the emirate next to Dubai. In the morning all the traffic comes from Sharjah, and in the evening it all goes the return direction. The Exact same trip from Business Bay in Dubai to Al Qusais might take 15 minutes or 60 minutes - but the time is entirely predicable - Uber just doesn't seem to do it here.
