In a county with woefully slim public-transportation options, Miami Beach planners looked out their windows, past the backed-up traffic at the stoplights, and saw the future. It was pretty, environmentally friendly, and didn't cost a lot. The ElectroWave shuttle buses premiered two years ago and have proven to be a wonderfully hassle-free way to navigate the often congested streets of South Beach. And a good thing was recently improved: In April the routes were expanded to cover more city blocks north of the original South Pointe-to-Seventeenth Street loop. Plus the fleet grew from seven to eleven vehicles, and payment options were increased (you can now use your parking debit card to pay the 25-cent fare). The shuttles are completely electric, with propane-powered air-conditioning units. "We are the only all-electric transit system in the country," exclaims Judy Evans, executive director of Miami Beach Transportation Management Association. "We've become a model for other cities."
