Contract-free cellphones, declining marriage rates and car-sharing services all tell us you're a bunch of commitmentphobes. Lucky for you the world is willing to oblige your wishy-washy ways, and for those who also happen to have a bit of a green streak, Connect by Hertz offers hourly rentals on electric cars. After launching its EV rental program here in New York last year, Hertz promised to expand to several other cities and countries by the end of 2011, with London being the next to go online this Friday. British urbanites averse to car ownership will be able to pick from a fleet of vehicles including the iMieV, Nissan LEAF and Renault Kangoo, range anxiety diminished thanks to the city's 16 charging stations. It's not exactly the Jetsons, but if this is the future of transportation, we're ok with that -- we're thinking Mother Earth is too.
