In my many years of driving and the many countries that I have driven in, I believe that Costa Rica is the worst.
I classify professional drivers as, police, taxi, truck/delivery and bus drivers. These so called professionals in Costa Rica suck, they are all headlight rude among other things. Why do they need four high beams and two sets of ultra bright fog lights for when the drive is at night and will not dim them if you flash your lights at them.
I also think the police need to set up a sting operation in Caldera and watch several of the bars where the professional truck drivers suck up 10 beers and several shots of whiskey before jumping back in the big rig for a night drive to San Jose.
