Changes

It seems to be much safer, faster, and informative to ask drivers at roadside stops such as gas stations and truckstops. Standing on the road with a thumb out can last for hours, and is really a last resort. If you want to go far, go with the truckers. They will carry you sometimes over 1000 km, and leave you at a good place to continue. Just keep asking. When you're looking for a ride at truck stops, keep an eye out for Brazilian and Chilean plates. Truckers from these neighboring countries are usually much more willing to give you a ride than the Argies, who will bullshit you about the transport company having sensors in the seats and harsh fines for taking riders.
