Yeah, that's great for people who don't ever have guests who can't play it on manual. If you have to go back out to the main menu to change it every time you pass the controller to your mate then it's roughly 90 seconds of watching a loading screen each time that could have been spent playing. Christ! What's so hard to understand?!
Oh my god man, what's so hard for you to understand?!
You don't have to go out to the main menu to change to AT. You only have to go to the event screen with the starting line up and the track in the background. Then go to driving options and change it to AT. Shouldn't take much longer than a normal restart. You don't have to wait for the track to load or anything, definitely not 90 seconds.
At least 3 people told you this already, but cause you're so up tight about this, you say THEY didn't read your post, when it's YOU who can't seem to read or understand what they're telling you
