Transantiago: before and after

Hello!
Today I'm going to tell you about Transantiago.
In my opinion, Santiago's means of transportation are getting better everyday. You can tell the difference between the micros before and the ones now in different aspects. I think I should start comparing the payment ways. We used to pay the bus driver with coins when we got on the bus. That made the process slow sometimes, but the drivers where very used to it. Now, we pay with a card that must be charged before you get on the bus. This makes the process a lot faster and cleaner. And, of course, the drivers aren't as exposed as before to thieves.
The new buses are cleaner, or that's what authorities told us. The ambiental subjects can't be forgotten.
Santiago's pedestrians have had to learn the new routes that have been implemented. This has caused a lot of trouble to many of us, because we have had to change our usuall ones. But, we have been pacient and the results can be seen everyday. Of course, accidents happen everyday, eventhough they can be prevented. Transantiago has been object of a lot of criticism by everyone actually, but we can't forget the fact that it has been constantly improved in this years.
