According to Newton's third law of motion, the force of the bug on the car is equal in magnitude to the force of the car on the bug. This means that the bug exerts the same force on the car as the car exerts on the bug when they collide.
Friction is the force that acts against all moving objects, slowing them down. It is caused by the contact between the object and the surface it is moving on.
A windshield wiper moving back and forth across a car's windshield is an example of intermittent motion. The wiper moves in a cycle of starting and stopping, creating intermittent motion to clear the windshield of rain or debris.
The force of the car on the bug is equal in magnitude but opposite in direction to the force of the bug on the car (Newton's Third Law). This means the bug exerts the same force on the car as the car exerts on the bug.
An example of downward force of air against a moving object is drag. Drag is the resistance force exerted by air on an object moving through it in the opposite direction. It acts to slow down the object's motion by creating a counterforce against its movement.
Trees are moving due to the wind blowing against their branches and leaves, causing them to sway and bend.

Start driving with your air conditioning on defrost, the AC will defog the windshield but you need to be moving.
They are moving faster

Did you try moving the wipers arms a notch or two so when they start they are not at the bottom of the windshield but rather an inch or so above the bottom edge of the windshield to make them sweep farther to the outside?
You are not moving, if you are comparing to the car.
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.
Linkage disconnected or broken
If the motor is turning, but the wipers are not moving, then you have a broken or disconnected linkage.
It could, but it would be more likely to strike a metal part.
In California, a cracked windshiled is a 'fix-it' ticket. Go to the nearest California Highway Patrol office to have the cracked windshield infraction signed-off.
