In your scenario wheels are controlled by position on road, steering wheel and engine. They do not slip you said. So wheels are forced by steering wheel to more through a certain trajectory on road. These trajectories have different length for the two wheels. Without slipping they will roll through these trajectories apparently for the same time but with the outer one with a higher rpm to compensate for the distance. Open differential allows for this speed difference. That's all. | |

In the scenario shown in the film, increased resistance on one wheel (grasping the wheel with your hand) causes the other wheel to speed up. But rolling resistance does not change when the car is making a turn, and not only that, but if it were to increase, it would increase in the outer wheel. In that case, the outer wheel would slow down and the inner wheel would speed up, which is clearly not what happens in reality. | |
