I would wager they will update eventually, but to be honest they could keep the events the same just increase the rewards... It's not as if Bob will complain about having to keep going round the High Speed Ring for 10 minutes in a Nascar 50 times a day...
If I was, then I'd probably have to kill myself. Thank God for Bob!
at the start i was kind of hoping you could create your own races (6 laps Laguna Seca, 10 laps Autumn ring, ect) and choose your own type of cars high or lower hp,
but i'm not complaining with what we've got here
