ch9 hates cars, actually they hate good shows. They always stuffed around the F1, all their previous 'car review' shows were crap.
They always broadcast the good TV shows they had at random odd late hours too. I mean random as in different time slots each week or not showing them at all certain weeks.
I was sad when ch9 got the rights to au TG, not because of the product (it's pretty good actually), or the ads, but because of how they would treat it, ie deliver to fans wanting to watch it regularly at scheduled times. Also because of the ratings, the show might suffer as the casual fan gets sick of random showings, ads and schedule changes and just get the torrent, so lower ratings may kill the series just because or ch9's arseholery stopping people watching and waiting for the torrent.
