The career mode in PC was confusing to say the least. I had hoped they'd simplify things with 2 but no.

I've just won my first championship in a tier 2 event but notice that all the while I'm progressing I can't go back to take part in the events I skipped in the previous tiers. Why??

Please tell me that at some point all the events across all tiers become unlocked??

If I have to create a new driver each time, just so I can go back and take part in the events I missed, then it's madness! There's simply no logic whatsoever to locking events in previous tiers!
