Africa Special, Part 1 - S19-E6
Corrected entry: Halfway though the episode Clarkson, Hammond and May encounter an impassable river which they cross on a home-made car ferry, dragging it across on stout ropes. The river can't be all that impassable - how did they anchor the ropes to the opposite side before the first crossing? Don't tell me someone swam across - the river is infested with crocodiles.
Corrected entry: During the 24 hour race, it is made to look as if The Stig reaches the end of the pit lane with seconds to spare. But as he sets off, there is a yellow car behind him, which wasn't there in any shots of him driving down the pit lane.
Correction: The Stig reaches the end of the pit lane as described - as he drives down the pit lane, one shot shows the cars on the race track coming into the finish straight, so he did indeed reach the end of the pit lane with very little time to spare. Just because another car arrives after the Top Gear car does, it doesn't invalidate statements that they were only seconds from being disqualified. As for the yellow car, we don't know exactly where it comes from - it may have been from a garage close to the pit exit, in which case it would not have been seen in the shots of the Stig driving down the pit lane and would have had time to get into position before time ran out.
Corrected entry: In the episode where they are testing the cars by British Leyland, James May bought a 1978 Austin Princess, and said it was the first car to "obscure its wiper spindles" when in fact, it was not. The Dodge Challenger had that in 1970.
Correction: He means the first British Leyland car to have obscured spindles. The Chevy Corvair, for example, also had hidden spindles, back in the '60s.
Top Ground Gear Force - S10-E11
Corrected entry: When Jeremy concretes over Sir Steve Redgrave's lawn, you can see the matting they put down so that they could clear it up after filming.
Corrected entry: During the America special, the squirrel they find by the roadside is a grey squirrel. But, when they prepare to cook it, it's a red squirrel.
Correction: The red squirrel is not native to America, so unless you're seriously suggesting that the production team brought a dead squirrel with them, just in case, I think it's safe to say that this is purely an illusion due to changing light levels.
Correction: Their adventures are always accompanied by well equipped experts and the camera crews. They have the necessary equipment to cross the river, but the challenge was for them to design a way for the three of them to get their cars across. They use the equipment to help them build the solutions. Regardless, on this occasion we see James paddle a small canoe across to secure the ropes.
