And you learn a ton about the physics of driving
When compared to motorcycles, it's fair to say that cars are rather stable. They have four wheels, they cannot simply fall over, there is less chance of injury, and at slow speeds, they're easier to manage. What that means is that suspension and steering dynamics are very, very different on a motorcycle, and you can feel subtle changes far more than when you're driving a car. Because suspension changes are more noticeable, you're forced to fine-tune your steering and throttle usage.
The end result is that you have a much greater sensitivity to what's going on with your vehicle, and a solid appreciation for how your every action impacts it. At the end of the day, you're a safer driver with greater control when the world around you gets dicey.
