Okay, since I was complaining about it in the earlier version, the first thing I did was go drive the two aerial tracks to see if anything had changed with the handling... and I'm sorry, but I'm just going to be brutally honest about this... They felt a lot better, well done.
There were still couple "okay wth was that then?" -moments, but I'd say ~75-90% of the incidents I had in this version felt like clear driver error. Whereas before it felt more like ~25% of the times being driver error, with most incidents feeling like the game just has quite arbitrary physics. The feeling between driving on the ceiling compared to the ground now felt far more logical and predictable to me than before. I don't know if you actually did anything to it, or if I'm just enjoying the placebo.
