Electric cars represent a tricky balancing act

摘要

Not long ago battery-powered cars were seen as a bit of a joke. No coverage of the technology was complete without a gag about milk floats or a sniggered reference to the Sinclair C5. And the diminutive G-Wiz, the first all-electric car to appear in anything like significant numbers on UK roads, did little to dampen the derision. Many of these preconceptions have been dismantled over the last few years, perhaps most dramatically by the Tesla Roadster: a high-speed all-electric sports car thatrnhas left all but the most entrenched petrolheads purring with admiration.
