Last night's Top Gear featured a race through rush hour London, from the western to eastern ends(?) of the North Circular.
James May drove a Chelsea Tractor. "The Stig" took public transport. Jeremy Clarkson went by speedboat. Richard Hammond went by bike.
2. Speed boat
3. Public transport
They didn't go into a lot of detail about the times, but public transport beat the car by 15 minutes.
