Sure a lot of Dominicans are poor drivers. We know and accept that. What gets me are the gringos who have adopted many of the same bad driving habits. Yeah, one must adjust your driving habits to the flow of traffic and the expectations of other drivers in this country but there is no excuse for running red lights, vehicle lights that don't work, passing on blind corners, passing too close to cyclists and motos, yacking away on the cell phone, the stupid things that we all know you shouldn't do
All 100% true!
But if you know that's what they do, at least you can be better prepared and plan for an "out." This is what motorcyclists do, and one reason that motorcyclists tend to be the safest drivers: the risk management skills necessary to survive on two wheels---generally threat analysis and planning---are easily transferred to a 4-wheeled vehicle.
Red lights: I wait at least a full second and then do a deep scan in all 4 directions at intersections, signaled, stop signed or not. You know a vehicle may blow through the intersection, so look for it.
Vehicle lights: never assume they work, period. If they work, bonus. Expect the unexpected.
Passing blind corners: always look for an "out." Keep on mind that what *you* see as a two-lane road, is ~actually~ a three lane road with the middle lane first come-first serve" in Dominican driving culture. And recognize that you may not have a good out, accept that risk, and get to a better situation quickly as possible.
Passing too close: yep, happens. You have 6" of "personal space" between you & other traffic in the Dominican driving culture. YOU can always offer more space. I certainly do.
Yacking on cell phones (texting is worse): yep, happens. So *assume* all are yakking, understand their attention may not be acute, and plan for the unexpected.
Defensive driving in the DR takes on a different definition than in the states or Canuckia.
And accept that some risks cannot be properly mitigated, like 3 drunken Organ Donor Wannabe's with a nearly empty liter bottle of ron on a crappy black passola, sans lights, at night, in the rain, going 30kph under the limit.
S#!t can happen on DR roads. Either understand the risks and employ strategies that mitigate it, or stay at home. Simple solutions.
