I live in Versalles, and there are perhaps four to five streets where you are likely to pick up a taxi within a few minutes, so there are certainly areas where Uber may be important (I realize Uber drivers are unlikely to be hovering around Versalles). However, while I generally like the idea of Uber shaking things up a bit, the service has to be worth it. I am already tired of having to act like a navigator to taxi or remise drivers, so if I have to it with Uber I am unlikely to use it much. Its not too disimilar from a remise service, aside from the fact you can pay upfront and may get a better card.
Seriously, someone said in another thread that remise companies offer better cars. Where? All the ones I use are terrible cars, some of the cars I have been in this city beggar belief. I hope Uber is not the same.
