Ladies and gentlemen... this is Mexico city

There's a project called 'Metrobus' here in Mexico city (the red bus behind the man). They've recently created more stations in order to cover more places of the city with this service. But apparently, it was not in their plans to put traffic signs in the streets and instead of using the metal bars and the signs that are normally used, there are people holding them to prevent that the cars obstruct the bus' way.
I was really mad because it's a very long street and there are a lot of people holding these signs and suffering the noise of the cars, the traffic, the people, the heat ... and without moving... as if they were statues!
