Hi dear friend @josevas217

and on odd numbered days (3-5-7, etc.) cars with license plates ending in an even number cannot circulate.

the famous "pico y placa", something that I have experienced and it really works, the police see someone driving and fine him if he is on his stop day, now about the CO2 reduction, let's wait and see, where I live there are several Tesla but there is still a long way to go to reach the 10% you are talking about.

god bless you
