I think the issue with TG and GT is the content no matter how quick they can get the show to air, it's already late content. Auto Car, Auto Express, Car wow, Car Flection etc on Youtube will of had this review weeks, if not months ago. People want reviews as soon as possible and that's why Youtubers smash the content and upload at least bi weekly. They wouldn't do this if the views didn't want it. Standard broadcast cant do this as the filming would have been shot months ago.
Its like when GT Series 1, Episode 1 did the hypercar review, the La Farrari, P1 & 918. The content was old before it had even been released. This part of TG for example will always be its downfall sadly.
