On Top Gear, Jeremy Clarkson showed off a car so damn tiny that it hurts to ride it. Or well, it looks pretty painful at least. Called the P45, the car is more like a go kart than a real car, based on a quad bike, but it's cute in a ridiculous way. The helmet serves as a roof and windscreen, the armour he wears while driving the car is the car's body and it looks fun as hell... until you hit a pothole and get smacked in the tailbone. I want a future where everybody drives these mini cars! [YouTube via Slate]
