Getting around in Santiago

If somebody ask me to describe Santiago de Chile, I would say its pretty much alike to Lima, same polluted, but more organized, secure, cleaner, but unfortunately, more expensive. No "combis". The bus, called "la micro" its a very old and noisy machine, but its being replaced by more modern european style buses. I cant say Im a big fan of "micros", but I am of the subway...subways are cool!. Public telephones are not dependable, you gotta get a cell phone in Santiago if you dont wanna miss the party or wait for hours in the meeting point. Is it hot in Santiago?...damn yes!...but theres also a cold wind early in the morning and at night sometimes. Streets are not made for wheels in Santiago, unless you dont mind getting stuck in holes and stumbling all the time. Pedestrians have the preference when crossing the streets, but you better dont trust the driver to wait for you unless your crossing with a big crowd of people. My biggest respect to the police. No corruption, no bribes, polite, always of service, 100% trustful, so far.
The worst: noise, holes in the streets, public telephone and prices.
The best: subway, police, big green areas, security.
