One thing is the teams self-driving on secondary roads or not so crowded routes as in Salta (or Mendoza, or the Patagonia) and something different in the city of Buenos Aires and the province of Buenos Aires, where is concentrated almost half of the population of the country.
Keepcopz, I know the road. I did it a lot of times while going to Pergamino - that is located two hours distance from San Antonio on the same route - for work, and although the first part of the travel is on a highway, once you take the National Route 8 it becomes a single lane route that is used not only by cars and buses but also by hundreds of trucks carriying from grains to livestock and manufactured goods. And after watching the numbers, probably you have already figured that we are not the most disciplined drivers of the world.
