The UK, famously, has this too. There are numerous accents present which have very small and clear boundaries. You can hear different accents after walking only a mile or two away to the next village, or the other half of a city. Oddly fascinating, and something I really miss now I've moved to a different country - a country which to my ears sounds very much like there are only a couple of accents.
