Yes. Corporate cages. This is a huge complex called Samara Shops. They thought it well, if you are going to be caged, at least have some minutes for window shopping or actually buy things they might never use.
I couldn’t find how many bikes are used in Mexico City on a daily basis, but believe me it is a great number. Just on weekends where main roads are closed during the morning to let bikes roll, there are approximately 70,000 bike riders.
