Hundreds of electric vehicle enthusiasts have been assessing the new age of driving in Australia. The fourth Melbourne electric vehicle expo was a chance to discuss their virtues and potential hazards. A ‘one-man-band’ greets visitors to Melbourne’s fourth electric vehicle expo. An old-fashioned way to showcase what could be the cars of the future. Electric powered cars, bikes, buses and scooters are becoming big business. They don’t make much noise, but their owners do love to toot their own horn. Dozens of electric vehicles of all shapes and sizes were on show at the event. Organisers say it’s about informing the public about the latest technology, and potential hazards.
