Friend of mine told me about the app today. Brilliant idea. On demand car service done via an app (or texting). Car is usually a town car, escalade, etc. Fares are reasonable. Drivers rate the passenger and vice versa. Your CC is charged (including tip) so no money exchanges hands. Only available in NYC, DC, LA, SF, boston, Chicago and a few other cities. Anyone try it? I will try next time.
