Has anyone noticed that when driving 70+ kmh and spraying the front window washers, the left wiper’s spray is also activated (which is fine) but because there is hardly any wall between the glass and the body frame, the fluid flows over to the left and splatters the driver’s side window in front of the left side mirror?

I think all my previous cars had a side wall that was a little higher than the front windshield, and would thus prevent excess washer fluid or rain water flooding over the driver’s left side window.

Yes, I've gone to waiting until I'm stopped or off the highway unless absolutely necessary.

Just make a sharp left every time you use the windshield fluid. ?

I have observed this on several vehicles including rentals and my previous Jeeps- the aerodynamics for fuel economy and reducing wind noise do not consider washer water flow. For me, a smaller squirt does the trick unless you hit a swarm of locusts or breeding mayflies and pulling over is the best option. Nothing worse than being on a trip in bad weather and having the reservoir run dry anyway.

I'm just going to use plain water. That way when it flows over my window it shouldn't leave a residue.

That will do little to help. Best additive I have tried that actually cleans stuff is Sonax. Make your own fluid to whatever strength you want be it with dH2 or washer fluid that you fortify...what I have done for years.

Absolutely, it's happening every time. The liquid gets collected in the corner, right behind the mirror. Moreover, during my recent trip in the really temps and freezing rain/ice,when I had to constantly spray the windshield, the most important. part of the driver's window completely froze up(see attached upside down? picture) and I had to use the manual airflow selector to direct heat towards it and be able to see the mirror. Never in my previous cars (Q5, GLC, Touareg) I had experienced such poor aerodynamics/ washer fluid/rain collection on the driver side window.
