PVR is spot on. I have grown tired of politically correct %100 non offending speech. Yes! Clarkson pokes fun at us Yanks and our hideous cars. I could get mad at him for it. Trouble is. He 'usually' gets really close to the truth. TG's show is all about Automotive Infotainment. I enjoy it.
Fifth gear is good to. And if FG starts to pull ratings from TG. TG will have to reevaluate and make changes. For now TG is on top and doesn't need to nor shouldn't make sweeping changes.
I think the British are spoiled.

Two good car shows and much complaining. Look at what we have had in America for entertaining auto programs. Zero, Zilch, Nada. I can't make a judgment about TG America as I have never seen it.
Our shows. Motoring or otherwise have one thing in common.
American Chopper: Unrealistic deadlines for a build, followed by much anger and yelling.
American Hot Rod: Unrealistic deadlines for a build, followed by much anger and yelling.
Cake Boss: Unrealistic deadlines for baking a cake, followed by much anger and yelling.
Jersey Shores: Gather a bunch of half wits and watch all the anger and yelling.
Kardashians: Same thing. But with more money.
I may be wrong. But I see a pattern here. If one wants to be annoyed, Just tune in the shows I mentioned.
You folks have some good tv. Enjoy it. It can get worse. Better yet, just throw a brick through the tele then go for a drive.
Cheers
