Fastest taxi in the world?

Are you in a hurry to meet up with your client to close that multi-million dollar deal? Well, what better way than to hop into one of these Lamborghini Murcielago taxis? Unfortunately, it still won’t be able to beat a traffic gridlock, regardless of its 6.5 liter engine that spews out 633 bhp, hitting 0 to 60 mph within 3.4 seconds. I wonder what the fare is for sitting in one of these. Would an American cab driver driving one of these actually arrive at your destination faster than a French cabbie sitting in an ordinary Renault?
