If you thought Top Gear might calm down a bit and the presenters start to act their age, well, you're wrong. Series 10 is one of the most ambitious yet, featuring some challenges that only the very brave - or the very stupid - would dare to undertake. For example, who in their right mind would attempt to drive through the Kalahari Desert in three 20-year-old bangers? Or try to cross the treacherous English Channel in a fleet of amphibious cars that are less seaworthy than the average church? You guessed it - Top Gear's three intrepid presenters Jeremy Clarkson, Richard Hammond and James May!
