Interesting thread.

I've driven in many countries all over the world including quite a few in Latin America. I am used to and expect to encounter potholes, various animals on the road, cars with poor emissions, poor (or no) lights, and overloaded trucks. But having just returned from Peru, I can say that we have a new winner for "craziest place to drive." Driving in Peru made driving in Thailand look like a leisurely cruise through the countryside.
Man, they are agressive in Peru! Driving from Lima to Huaraz - about 6 hours, we almost got hit head-on TWICE! People just cut the blind corners on the mountain roads without thinking that perhaps another car may be coming the other way. In the cities, lanes mean nothing, the air quality is awful because all the cars are belching unregulated emissions and traffic lights and stop signs are merely suggestions. Constant horn honking completes the picture.
We also got one flat tire, and had to bribe a cop in Lima. Next time, I think we'll hire a driver.
