What car are you using ? What kind of bump ? I don't see the roof of the rally vivace caving in after a jump
Please use the latest game version. What you're describing is 2013 type stuff. It's pretty much flawless nowadays.
Johnson Valley does indeed have a problem with cars getting stuck in stuff, and yeah they can get stuck in each other on high speed impact. It has not been addressed simply because it's hard to fix. But you just completely changed the topic lol, your original point was that physics feel like jelly which is not true.
I simply have never seen car rooves cave in or things like that and i want pictures so that we can tell if it's your game that's corrupted, if the cars are indeed jelly-like, or if they're fine
If it feels unrealistic, it's because nobody would ever do something this extreme with a car. Although yeah at high speeds things can get a bit shaky
but genuinely what cars are you driving, what version are you playing, and what maps are you usually on
