Due Argentinian holidays, there are more and more families arriving in their own cars day by day, in Bariloche and The Lake District.
Plus many people with RV, campers etc...even more bikers along Bustillo Ave...it is a real mess
Beware also with chilean and brazilian drivers...which they are a little absent-minded in time of driving.
Drive slowly, keep an eye while driving...use hazzards when you want to stop and blinkers when you want to turn, be respectful with pedestrians and bikers...avoid downtown Bariloche during bank hours ( 9am to 1pm).
Enjoy your stay, and relax while driving..., and take enough time if you have to catch up a boat tour, a flight, an excursion... or whatever
