update: Lyft has now lowered their prices to near match Uber. Both Companies are dirt cheap all over Vegas, about 1/3 the cost of a taxi.
As usual Uber comes to a new City and test the waters, if all is great then they keep their rates high enough for the drivers to be able to make a profit but low enough for the riders to want to use them. But Vegas has not embraced the ride sharing as of yet so Uber drastically reduced rates so low that drivers will drop like flies but riders should increase. As of Dec 14, 2015 Lyft has not followed suit. Lyft is still charging the original rates. Usually Lyft will change rates to match Uber within 24 hours but this time they have not. The question is: will all drivers switch to Lyft so that Uber will have to raise the prices to get the drivers back or will all the riders only use Uber so Lyft has to reduce the rates? If You have no drivers, You cannot have riders, right?
Update: July 2017 Uber and Lyft are now picking up all over Vegas. Operations started on September 15, 2015 and so far all is going smoothly. There are no restricted areas for use of the ride share services. Both Services are operating at the McCarran Airport. Now Uber has drastically cut prices many times. The base fare that was 2.40 is now 1.12, the price per mile was 1.85 is now .675, the per minute price was .30 is now .1125. A Service fee of 1.38 and booking fee of 1.90 will be added to every trip. There is also an Airport fee of 2.45. Lyft is mostly the same except You can tip on the Lyft App but cannot on Uber. Drivers are allowed to take cash tips on either service. The low rates have made it near impossible for drivers to make a profit and even though that is terrible for Them it is great for the riders. You will see that service is fantastic, cars are ready to pick You up all over Vegas. A short ride to the Airport from a nearby hotel will typically cost 12-13 dollars but only about 4.50 of that will go to the driver because of all the fees that are added. Uber is expected to add the tipping feature to their app by the end of July 2017.
