SSelf-promotion is something the boys over at Top Gear have never had a problem with, and as part of the build-up to Top Gear Live, they've pulled out another stunt ready to become an instant classic: Driving a tank across the Tower Bridge following a line of supercars. Why'd they do it? Although initially we thought maybe Clarkson's ego finally convinced him an invasion of London made sense or perhaps Captain Slow finally found something to drive that he felt he could keep up with. No, in reality the Tower Bridge stunt was part of an attempt to promote the live stage show kicking off in the UK this October before it goes global. All we know is, although it was an interesting play, we'll keep our remote-controlled tank, thank you very much.
