Poor cleaning performance in bad weather impairs this faculty. The wind lift factor further reduces the pressure on the blade at highway speeds, when driving against the wind, or when both conditions occurs. The steel of the original spring within the arm is stressed to its limit and cannot generate the required pressure. The arm does not offer sufficient space to house a bigger or stronger spring. Gives the best visibility at all times.
Most drivers are aware of aerodynamic wiper lift.
Necessarily, if the pressure on the blade were greater, wiper lift would not occur. An aerodynamic blade minimally compensates the effects of wind lift but does not correct the lack of pressure on the wiper. Contributes to your driving safety and comfort. When driving a vehicle, you must see where you're going and what the driver ahead will do. Bad visibility due to a poor performance of the wiper system makes driving risky and unpleasant.
