As you say, they act as they don't need anything to prove. In my opinion that's why they lost the soul. Also the format of the show is changed, don't get me wrong but as an "entertainment show" there are plenty of shows around doing far better. Clarkson and others role of "an entertainer" is not something that they can really manage. It shouldn't be in the first place.
They have already lost their chemistry Top Gear in last few seasons.
Their time is passed
