I would tend to agree but Jay Leno is a widely known auto enthusiast that has access to millions of viewers on a daily basis. I imagine that a good majority trust his opinion and will follow suit of his decisions based on his popularity and perceived aficianado of autos' status. I would trust his endorsement of an h-car waayyy sooner than say Conan O'Brian or some random middle class citizen that may or may not even know who Chris Bangle is.
