Mexico City: the metro is 5 pesos, and Uber is the taxi

The Mexico City metro costs five pesos a ride on a rechargeable card, and it's the fastest way across a city of chronic traffic; avoid it in rush hour if you have luggage, and note the women-and-children cars at the front of trains. For door-to-door trips, locals use Uber or DiDi rather than hailing taxis on the street, and the app's fixed price removes the haggling. Sitio taxis from a marked stand are the other safe option.
