Concept cars! What are designers thinking of?

Concept cars are supposed to give us an idea of what to expect from the car makers in the future, but sometimes these designs turn out to be so far away from the mainstream that we can only class them as weird. So now we have this graphic from Vertu Lease Cars, which shows us some of the weirdest concept design cars ever created. These designs may have looked futuristic at the time, but now they seem just weird and who in their right mind is going to pay out big money for a weird car? Lots of people it would seem!
