ELI5: How do bugs manage to stay stuck to car windows whilst travelling at high speed? Are the suckers super strong?

It is partially due to the boundary effect. Basically, air that is touching the car is not moving relative to the car (air is sticky) but assure further away is moving (again, relative to the car). The boundary layer is the area Close to the car where the air is moving slower. IIRC this boundary layer is a few centimetres thick, so anything small enough doesn't experience the full air speed.
