I wonder why that is...truly not because Polyphony have done no work (instead making AI stupider and more prone to binning it in corners) in such a thing, and believe that keeping the status quo in a game that is putting so much emphasis on the single player portion of the game, like GT7 is, is a good idea?
The best part about this laughable excuse is that bad GT AI, over the years, can be a direct cause and effect with regards to the absolutely horrific driving habits formed by online players in ultimately the most important part of GT Sport (and indeed, what Polyphony expect you to play) is simply the chickens coming home to roost, where players have been conditioned by the games previous (mainly through moronic and slow AI, and absolutely no consequences for being overly aggressive, especially damage wise) to treat AI like dirt, and subsequently, online players?
Scaff's post from early in the thread underlines just how off the ball Polyphony are in the AI department, that they are getting beat out by teams much smaller then them, who are able to provide AI that know how to race and to put up competitive races. Instead, Polyphony decide that online racing is a better barometer for racing, and basically kick the can down the road for another title before this very same thread crops up when we're in the lead up to GT8's release. What the hell is it going to take to see some actual change that simply isn't 'well, race online you idiot'? Because the issue of bad AI ultimately effects online too.
