Tweaking Vehicle Collision Response

Hey, I'm hoping someone can point me in the right direction as far as the code. If I wanted to change how a vehicle responds (physics-wise) to collisions with certain types of objects, where would I make that change?
Right now I have a vehicle colliding with a ShapeBase-based object, and the vehicle stops as if hitting a wall. I'd like the object that is hit to be thrown out of the way (which I've got working) and the vehicle to continue moving while only losing a bit of its speed/momentum.
I was playing with the Rigid::ResolveCollision function and trying to modify some of the forces in there based on what kind of object was hit. Am I looking in the right place? Thanks.

I would have a look at Vehicle::resolveCollision before the same method in Rigid. Otherwise you'll be applying the same changes to all Rigid objects. I think at the moment the vehicle will apply a force to stop itself dead, and won't calculate any forces to push other objects. You'd want to reverse that - perform all the calculations on the colliding object and apply forces to it and just a little bit to the vehicle.

For script though look for applyImpulse.
