These are the reasons you should always use Uber instead of taxis in Mexico City. 1) Price is fixed and fair. In a street taxi, the price is sometimes negotiated (even though all taxis have a taximeter) or taxi drivers may overcharge if they notice the passenger is a foreigner. Uber shows you the price before you accept. 2) Safety. Every Uber ride is tracked by GPS, the license plate, driver's name and photo are in the app, and you can share your live trip with a friend. 3) No cash needed, no Spanish needed. You pay with your card in the app. No need to argue about change or explain the address in Spanish. You just need to type your destiny and it takes you there.
