Today I visited my 93 old Mom, which means in total 220 km highway with speeds between 100 and 130 kmph, with the side screens off and wind deflectors on, this provided me an opportunity to experiment!
Me moving front and back--to "study" the distance from windscreen effect--must have looked strange to other drivers. However, for science one has to make sacrifices!
It is clear that shorter drivers have an advantage over taller ones (not because they sit lower, but further back: more turbulence). When I move forward/backwards, clearly turbulence decreases/increases. Also, the stream of air that comes into the cabin just back from the side mirror (as discussed above in this chain), can be greatly diminished by having one's arm just outside along the top of the cut away. I conclude that a flange like structure, secured like the side screens, could do the trick. I am afraid that one will not win a beauty contest with such balcony, but it should reduce the turbulence comming from there.
Another thing I learned is that, under similar conditions, Lindberg stick on sunglasses do stay on with side screens on, but blow off when they are not in position, and wind deflors do not provide enough protection!
There was virtually no wind today, so effects from driving only!
So far the experiments today!
Cheers,
Bert
