I drive from Jarabacoa to Santiago about 3-4 times a month and to Santo Domingo about every three months. I have been stopped twice by AMET , both times for making illegal left turns and both times my wife talked them out of tickets. The only PN we have been stopped by are at the roadblock they put up between Jarabacoa and La Vega ( near the Autopista Duarte) and never had any issues. I don't find driving here hard, although my body feels the tension after I get home.
Ditto, 5-6 times a month to Santiago, 2-3 times a month to Santo Domingo, the odd monthly excursions to other destinations, not including 120,000+km all over the country by motorcycle.
We've been stopped four times in 8.5 years: one blowing a red light I couldn't see, blinded by a high truck in front of us at Estrella Sadhala & Argentina, once in the same spot because of excessively tinted glass, two weeks ago on the Autopista for doing 15km over the limit and once on the Jimao road just leaving the Sabaneta de Yasica by the PN looking for documents when they still had traffic enforcement. No tickets, although no doubt the officers were frustrated.
We've been stopped three times by PN near La Vega looking for guns---always on weekends. One voluntarily cost a Gatorade (which we buy in bulk.)
We had a guest on a motorcycle randomly stopped by the Army between Nagua & La Entrada---one of 7 on bikes. Some outrage in English about "extranjero turismo" ended that one pronto.
Living in the DR is not for everyone, nor is driving in the DR.
IMO, it all has to do with adaptive behaviors: some cannot wipe the culture of their homeland from their brain, and cannnot cope with living out of that box. Some cannot adapt---which includes predictive behaviors---to the driving conditions here. Some fall prey to exaggerated anecdotes about supposedly predatory behaviors of the authorities. Some cannot abide by the #1 difference between the driving culture in the DR and that from which they came.
In the states & Canuckia, your "personal space" on the road is around 3.5-4'---if a vehicle or pedestrian gets within that radius, it's time to freak out. In the DR that personal space is about 6". If you can't deal with that reality, then you shouldn't be on the road.
Adapting to predictive behaviors is also critical: yes, a moto will cut in front of you. Yes, a car or truck will try to muscle into your lane without warning. Yes, people & slower motos are right off the road. Yes, motos will go the wrong way down a one-way street and act all manner the fool. Yes, that red light is merely a suggestion. Yes, "yield right of way" is a non-sequitur. Yes, that vehicle in front of you may just suddenly stop. Yes, all those cars around you between 5 & 8pm may have a drunk driver at the wheel, as well as any car on the road after noon on weekends. So understand the risks you face and mitigate them as best as you can.
I, for one, find the "rules of the road" here refreshing. While it can indeed be organized chaos, those who embrace the chaos can thrive. Those fearful of chaos will succumb, and shouldn't be here.
Always remember: you are the foreign body in the Dominican Driving Culture Petri Dish. It's up to YOU to adapt---or perish.
I wrote a short ebook that describes the driving culture of the DR along with suggested strategeries. While aimed specifically at motorcycling, it is equally helpful for cage drivers here. If you PM me your email address and preferred format---.pdf, .doc, .epub or .mobi---I'll be happy to send you a copy.
