When you request a car through the Uber app, they’ll send their own upscale sedans and SUV’s to wherever you are in the city, at any time (which you can track in real-time). Because you pre-load your credit card information, its a frictionless experience with no fumbling for cash (they also add gratuity, and will simply e-mail you a receipt). They also offer a more affordable Uber X. If you don’t have a Smartphone, you can text your address and city to UBR-CAB (827-222).
