Big problem with vehicles

[mikeman42]

I'm using the new Newton2.0. But I still have BIG problems with the raycast car. Basically, whatever I do it's impossible to get a steady vehicle that drives nicely on terrain and slopes. I've also noticed the same happens with demo, when the car goes up a slop it gets unstable. In my case, I just can't seem to find the specific values I need to set(friction,suspension length,springs coeff) to get a stable car. No matter what values I set, the car seems to be stable only one a flat plane. If it's a terrain, it jitters, jumps around, turns on its own and generally behave crazy. I just don't know what to do here, and there's literally no documentation. Any ideas that might save me? Thank you!

Mike, I'm not the right guy to tell about stable vehicle (my own is bouncing and jumping even in flat planes) but I would try to make it heavier and set more inertia to it. I think this could make it more stabler. You may try to soften the springs too ...
