You've been shown mate, made the claim that it was because we were braking, despite the video not showing any braking, and then you scurried off and said we were nitpicking.
For clarity, this is what I expect to happen when I hit a bit of a hard jump in a 4wd mid 90's sports car. I expect to be unsettled, I expect the car to bounce, scrub off some momentum, land, jiggle a bit as it's unsettled but land and be able to drive normally. A bit like, I don't know, how the known universe would behave. Like this.
What I don't expect, is for quite frankly, whatever happens here. Compression just turning into immediate rebound and lifting the cars ass over its head. Nonsensical physics.
It's not exactly a hidden piece of information that compression and rebound were horrendously broken in 1.49, persisting up to 1.52, so I don't know why it's so hard for you to accept that there might still be somethng a bit wrong with how the game is calculating things.
I'm still thinking it hits a hard cap on compression (to stop whatever was happening in 1.49 to launch cars to space) and that hard cap forces rebound to equalise the suspension - squishier cars like the Evo's hit that cap quite easily and therefore when it's hit, things start acting funny to try and get it out the 'danger' zone.
This was to me, pretty likely what was going on in 1.50, as you could straight up see the wheels kick back into place under heavy compression - and I feel like they've slowed down the rebound rate to try and kill it off for good, but it's still not working in some cars.
