I hope he finds an alternative venue and beats the BBC’s ratings. Not sure if he can, in the UK, don’t the control all the TV channels? Here, he could just go to AMC or TBS and do the same show.

Because its financed out of the public purse, it is not vulnerable to pressure from car manufacturers threatening to pull advertising revenue in the light of bad car revues (a problem that has plagued attempts to make an american Top Gear).
