I've got a 5 meter long car (raycaster vehicle), which can travel up to about 150mph (240 kph), once the velocities get up to this sort of level I seem to get artifacts, with no steering forces it'll still repeatedly veer off to the side.
Would I be better scaling everything, so the car is 2.5 meters long, and travels up to about 120 kph, or do the numbers sound reasonable to work with?
It's currently driving on a completely flat btBvhTriangleMeshShape, the triangles are fairly large, between 10m and 50m. I'm using timeSteps of about 1/60th, I've tried doubling up the sim steps but get the same result. Below about 100mph the results have been fantastic.
Thanks!
