Distribution and relative quantity of droplets in kg/m 2 are recorded in Fig. 5. There are shown the local extremes of the amount of captured droplets in all variants on the sampling zone 5. The highest local extremes of the number of captured droplets were recorded in the right-side variants. Specifically, in the front against the vehicle (variant 1) 0.275 kg/m 2 and in the back in the direction of the vehicle (variant 2) 0.124 kg/m 2 . In the case of the left wind flow side, the extremes would be an order of magnitude lower, specifically: in the front against the vehicle (variant 3) 0.0492 kg/m 2 and in the direction of the vehicle (variant 4) 0.0492 kg/m 2 .
