Wow, really? That's all it takes?
I think their definition of daily races is: 3 races run all-day over a period of one week. In PD's mind, Weekly races are 1 race per week, which is effectively what the FIA Nations and Manufacturer cup series should be.
All about perspective.
Also kinda makes sense to have these "dailies" be running over a week to allow for normalisation of leaderboards, race strategies, effective tuning techniques etc. Also allow for everyone a chance to compete in these events, some people won't log into the game every single day. Remember what the intro says: "Sport is for everyone"
Edit: Would have been better if they didn't kick things off with a dreaded oval Gr. 3 race though.
