Getting a Driver's License in Zihua - current info

I post on a few automotive forums on Qura and YouTube. When the subject turns to some drivers and the condition of their vehicles there are always the calls for tougher licensing requirements, more intensive driver training, mandatory auto shop in high school, strict safety & emissions inspections, etc.

Always get a kick out of telling them how laughable any of those ideas are where I live because one literally does not have to know how to drive, be able to read or even see a road sign to get a license.

Naturally that would result in total chaos...the entire country* would look like something between Death Race 2000 and the final scene in Used Cars. Except it doesn't.

There is a spirit of cooperation and give & take here that doesn't exist in the US, and it makes driving a pleasant experience. There is no road rage...at least not that I have encountered. Nobody sits in the middle of the lane with traffic piled up behind them while they self-righteously enforce the speed limit. When I slow down to turn into a driveway, there is not a horn blasting the instant my brake lights come on because I happen to have--for a couple of nano seconds--inconvenienced a BMW driver. But the best part is I don't have to maintain a constant vigil for ticket-happy (or even trigger-happy) cops. I can focus my entire attention on actually driving, navigating, and not hitting stuff.

*Do license requirements vary state by state, or is "no test required" true everywhere?
