Since the deregulation of the taxi business, the streets of south Scottsdale, Mesa and central Phoenix have been filled with colorful taxis bearing Spanish names and plastered with advertising for everything from Food City to chiropractic doctors. And Mayas Radio Taxis are one of the first and largest squads on the streets. Their cars are clean, colorful and come in a bunch of sizes, all bearing the large Aztec pyramid logo. Flag one down and you get more than a lift; you get a guide. Hop in and ask the Spanish-speaking driver to take you to the best local eatery or dance club. They seem to know everything! Their rates are $5 minimum and $1.25 per mile thereafter. And unlike their counterparts in Mexico, these taxis, for the most part, obey traffic laws.
