How does a scooter with a windshield work?

The front windshield of a motorcycle is commonly known as a "windshield". As the name suggests, it acts as a shield from the wind.
If you're not driving long distances and just commuting to work, it's okay to install a windshield. Riding a motorcycle can not avoid the wind and sun, after all, installing a windshield can play a role in preventing "wind blowing".
But the main role of the windshield is turbulence. Reduce the resistance of motorcycle driving, direct the air flow diagonally upwards, and avoid blowing directly on the body, after all, the direct air flow blowing the body will accelerate the consumption of the driver's physical strength.
If you install too large a windshield, it will not only increase the driving resistance of the motorcycle, but also increase fuel consumption. Most importantly, lateral wind will greatly reduce your control over the motorcycle, and the greater the wind speed, the higher the probability of the motorcycle losing control. It will bring unpredictable safety hazards to motorcycle driving.
To sum up, if you ride a motorcycle to work, you can install a large windshield to make your body more comfortable; If you ride a motorcycle at high speeds or long distances, installing a large windshield can put you in danger at all times.
