This caught my attention in The Times - Jeremy Clarkson thinks the Reva G-Wiz DC might help you save the planet "but you might lose your legs in the process" and:
There’s another thing, too. Children playing in the street can hear a Range Rover coming and know to get out of the way. The G-Wiz, on the other hand, is near silent, which means they may run in front of you to retrieve a lost ball. You may then hit them . . . causing your car to disintegrate and your legs to come off.
