First off, we are ever grateful for your undying dedication to giving feedback. It's helped us so much with development, and we hope you can see the changes so far that you have had a hand in. You've truly made a difference in development, and there's plenty more to go!
One thing that is not helpful though, is constantly posting complaints about the car catching on seemingly invisible geometry, bouncing/stopping for no reason when landing from a jump/fall, and intersecting with the world like it's trying to hump it to death (or simply falling through).
We are VERY aware of these issues, and believe me when I say that no one is more annoyed and frustrated by them than we are. It's an issue with PhysX and is not going to be easy to fix (but we will fix it, believe that). It will take some time to address
I see a lot of posts about these things, and to be honest, it's a bit demoralizing to be reminded of it so much when we're doing our best to fix it.
So please, do us a favour and try not to talk about it anymore. Yes it's super irritating when it happens, and we appreciate you still wanting to play the game even when something so super annoying occurs, but we are 100% trying to solve it, and reposting about it does not help.
Hopefully you don't see this as me being salty! Just trying to get my forum experience as optimal as possible so I can respond to as many posts as I can.

Again, we're so happy to have such a dedicated and active community, so don't let this deter you from posting! And if you disagree with my post here or want to start a discussion about it, please post below!
