Vehicles need more shock absorber dampening and brakes can pull your car back

I'm not exactly a car-tester nor have I driven many cars in real life, but in game i cant help but notice, specially when in the cockpit view, that all cars are way WAY too bouncy in stock form compared to other real life street cars. As in, it takes a good 5 seconds for the inertia movement of the springs to fully stop when in real life it shouldn't even take 2 with a stock suspension in good state. I have no idea if this is a default parameters issue or if the game physics have issues in the simulation of the shock absorbers oil.

Another issue i've noticed which may be related is the fact that some cars go backwards if you brake and you let go of the brake as soon as the car stops. It's almost as if the brakes "pull the car back" rather than "add friction on the wheels", and if you stop braking at the right time, some of that "pull" force can make it go backwards. Then again i've only tested this on relatively old cars (the gavril pony car) so i have no idea if this is due to an outdated brake logic being used that isn't applicable to the current cars anymore.
