I would say that sliding into an obstacle or a wall and less likely to crash, even with the same velocity vector, is still somewhat realistic. A simple argument is that sliding provides the car with a sliding angle. When in situations that the sliding angle partially cancels the trajectory angle determind by the velocity vectory, the car will have a smaller geometry impact angle to the wall or obstacle. If we just consider simplemindedly uniform mass and flat rigid wall, under the same velocity vector, the smaller the geometry impact angle, the smaller the impact.
