What Zach has been saying is that they hope to do something more like iracing as opposed to forza.
For those not familiar, iracing has a weekly race series for a given car in a given track. The races occur every hour or half hour, in between its open lapping practice. You get pulled into quali and then the race itself.
Points are awarded (or taken away) and over the course of a season, you visit a number of tracks. Point standings are tracked and at the end of season there is a winner. At least, this is what I recall, but haven’t played in a while.
This as opposed to the more casual games with lobbies that fill with folks there for different reasons. Iracing uses a split system, where drivers are grouped together in races by split. Top split are the fastest drivers.
How you drive affects two things: safety rating and license. You need both to go up I think to do faster cars and series.
