I want one. Maybe not for 50k quid, but I still want one: http://www.wimp.com/ecomobiletests/ Make you wonder why a major manufacturer like Toyota couldn't crank those things out for $10k. They have to be cheaper to build than a car, and being lighter they'd get better mileage.
And with accelerators that stick and bad breaks you'd be more out of control than a Luger in Vancouver.
