You have to take it for what it is.
Scripting a humorous romp through a rain forest isn't the same as doing it. Sure, they have some jokes written down, and sure, the challenges are contrived and set up to be close finishes, and they absolutely have some idea of what's going to happen before it does, but that's not the point.
The action is real. The humor is real, and the challenges are indeed quite dangerous at times, or at least incredibly irritating for the inhabitants of the land they invade for the episode. They don't pretend to be action heroes, they pretend to be television presenters.
What they don't need to pretend to be are three klutzes with millions in the bank doing incredibly funny things involving manly pursuits. It doesn't matter what they do, it's going to be funny, informative, and entertaining. Yes, I said informative.
I've driven a lot of cars, and done a lot of stupid things in various places. There is one skill they possess that is above achievement by any other program. They get the
feel across. From the cinematography, the cutting room, and even to dubbing, enhancing, and trying something many different ways, they show you how things
feel, in the best way possible short of experiencing it yourself.
If you haven't driven a car, and want to know what it's like, the first thing you need to do is see if they have reviewed it or used it in a challenge. You want to know what it's like to pilot a Ford GT, a Jaguar Xk, a Classic Mustang, or even a Ferrari? Watch the program. Crank the volume, use the biggest television in the house, and they will pour the experience out of the television and drench you with it.
EVERYTHING changes for each car. Everything. And all that adds up to an artistic, accurate representation of that automobile that is designed to tickle as many senses as television allows.
A fine example is the Aston Martin V12 Vantage:

Another great example is the Morgan Aero 8, though I can't find a video of the review to link. They perfectly captured the menacing, bulging, muscle bound meanness of the anachronistic monolith that is the Aero.
In their America special, many Americans learned what lurks just beyond the highway they travel down every day. You may not like it, but what you saw IS America. It was a vibrant, if harsh look at the massive, held together with hope and strings land that we call home. In their Africa special, the feel of the continent, at least the part they were in, was captured beautifully. You could almost feel the heat and smell the singed corn husks.
It goes for everything they depict on the show. Never mind the nonsense, the comedy, or the scripted antics. The overall effect is what they should be well proud of. They take all those bits, nail them together, and teach you something about the subject of their interest by masterfully blending all the aspects of script, improvisation, and production values together into what equates to impressionist art on television.

You learn something about anxiety. It can be uncomfortable, it has it's causes and cures, and it can be studied. You are educated by looking at the things in those links.

You fucking FEEL it. You haven't learned anything. You were simply exposed to a very small facet of the experience, the best our available media can provide.
That's why I watch Top Gear. They let me feel a part of what they are doing, no matter how pointless it is. Never has buying a junk car been more appealing than watching their road trips. Never has owning a boat made more sense than riding along as those buffoons tried to cross the English channel.
Well... That, and they are funny as all hell.
