There are a few interesting online options. You can force pit stops and/or tire compound changes. Qualifying can be with other cars or alone on the track.
I found dlrws6 online last night and the forced pit stops are kind of cool. If you do not pit it gives you a 50 second penalty.
Also, it is easy to find friends online hosting a race, just check the box.
Also, also, I hope to find a few more online today.
