In race A, for example, you can punt somebody off at one of the hairpins, putting them into the barriers and facing at least 10 secs of reversing out and getting going again, behind the whole field, when all you get is a measly 2 or 4 sec penalty. It's absurd. Should be 20 or 30 sec pens for strongly rear-ending people in braking zones, software must be able to determine whether people are braking or not. Even if player numbers dropped by 20% it'd be worth it. PD should put quality above quantity.
And to the guy who just keeps saying 'get better' in response to almost all complaints: no, this happens at almost all levels, and all players, all, deserve a decent experience. Some of us are not racing online day in day out, let alone ranking up 7k starts (I'm on 500 ish, in healthy doses over 4 years, only doing the combos i really fancy), and neither are the vast majority of us in nice rigs (let alone VR).
I don't think this is rocket science. PD just need to put some effort into improving things. It's on them, not the players.
