Maybe you have happened to catch the theme of my recent blog posts........Yes, that is correct that horrific state of transport in Lima. This next item - see the link to the story in Spanish from a great Lima newspaper Peru21.
The essence of the story is that there are thousand of informal combis - the little vans that somehow are considered public transportation - that circulate the highways and streets of Lima. By being informal they not normally not insured, the drivers are not paid adequately, and this basically gives them the right to do whatever they want - change routes, stop where they wish, etc.
Unfortunately, the authorities here in Lima really do not see this as a major problem and the typical citizen of Lima is also to blame as they - to save a couple of cents will continue to ride these death traps on 4 wheels until the authorities do something to get this vehicles off the streets.
Sadly, this solution is a long ways off in the future. Until then, when entering a combi do so with the knowledge that this is the cheapest unregulated thrill ride that you can find for under $0.25.
Enjoy!
