You are right in this particular case. CV may effectively solve this particular problem, but will be useless if yellow cars are replaced with blue trucks, or if starting angle will be slightly different, or if other cars will start moving as well, etc, etc. Genetic algorithm may be useful if one needs to animate cars in a game and making the algorithm less deterministic will make the game look better.
