I don't know where in Mexico the writter of the article went, but the road infrastructure in Mexico is quite good. Yes, there are potholed streets. But all main streets, those where you can go high speed, are pretty good. The potholes are not the main cause of road deaths, the main cause is drunk driving. And yes, there are alcoholimeter checkpoints all over the major cities. The fines are pretty high and you can be arrested for 3 days on first offence.

I feel this article is just bashing Mexico. The roads and the drivers are no that bad.
