Television has a long history of fakery, from the very first silent films to the latest HD spectacular. Don’t be naive, they all do it, every studio has an EDITOR!

That said, I think Top Gear does use excessive editing, and the presenters sometimes portray their exploits in a very dishonest fashion. Classic example is James May in the caravan airship; you’d think he’s some kinda hotshot pilot after watching the episode, but in reality he was just a passenger (the real flying was done by a trained stunt pilot). Not to mention the fake police helicopter and fake taxing passenger plane…
