I hear what you're saying Brandon. How much time can one spend on a racing sim each week? Even the hardcore among us (mostly single people) with gobs of free time, how many different cars are you going to drive in a 5 hour session? I'm a complete loser so I have tons of free time.
Still, if you want to get any meaningful driving in you need to spend a good amount of time with a car. 99.9% of my racing/track days are offline due to my health, so I just like to see totally random grids all the time. I'm sure the vast majority of people who like to race online with their friends will be jumping over to PCars 2 very quickly as pC2 is the new hotness, for sure. 18-24 months from now AC2 or another sim will be the flavor of the month and around and around we go.
