When I visited CDMX a couple years ago, I instantly noticed these things.
Green, older, dirty, and often being driven like something much smaller in size.
I've no idea what powers these things (ford 460?) -- but some of them sound mean and I spotted a couple manuel transmissions too. From a quick search, they're phasing these out due to emissions over the next few years, also they're informal so I'm sure authorities want to regulate them under regular transit laws.
Any other insight or similar setups across the world?
