Amazing car simulation

It's sounds silly but, is there anyway to archive this with GS?
Rigs of Rods Burnside Crash test
Gavril G2S in Rigs of Rods

sure, but only if you have the same skills as the developer of rigs of rods. and if you have those skills, why use gamestudio and not something like ogre (like rigs of rods uses)?

lol dude, you are right as always

In the GS manual, lookup VEC_TO_MESH.
VEC_TO_MESH is intended for deforming models and terrain in real time, infact the example code for that function is a code that puts a dent into a model by moving a single vertex inward by 10%.

I suppose you would get a crushed-in effect by causing the vertices at wherever the collision occurs to "match" the vertex positions of the wall you run into until your windshield comes close to the wall itself.
