I believe that the most consistently dangerous thing about driving Mexican roads at night is the often heavy bicycle traffic when all bicycles have no reflectors, no lights, drivers with dark clothing, and they zip from one side of the road to the other.
I certainly agree with you Garry that cyclists and pedestrians add significantly to the traffic related problems in Mexico (especially at night). We have to keep in mind though that Mexican traffic laws lean heavily toward protecting them over someone driving a motor vehicle. If an incident like this
can have such a profound outcome in the States, imagine the potential consequences of a similar act in Mexico. Be careful people - we're not in Kansas anymore.
PS - Rolly, I played with the quote & editing function and figured it out. Hope you're well.
