As drivers’ tolerance for rain on their windshield varies, it would be good to be able to adjust the “aggressiveness” of the automatic detection for the wipers. Currently, even the second (more aggressive) setting seems to low for many drivers.
Should be a minor software change without cost.
An improvement was made in the 7.1 software to have the automatic rain-detect speed work better. Not a user adjustment, but maybe enough. More improvements have been made over various versions to make it work better automatically.
Even the least frequent intermittent setting is too frequent. Our local driving conditions include days of very light or misty rain. I don't need, nor like what goes with a wiper setting that results in unnecessarily frequent wiper swipes. I have the same criticism of Mercedes auto/intermittent wipers.
I would simply like the car to lower the initial wipe threshold based on when I press the button to manually wipe once. I don't need a specific button or setting to click - it should be able learn my preference. I think my Model 3 is sitting there like "oh- there's a few drops on the window but not enough to wipe" and I'm like "is it going to wipe for me? I guess I should click the button" and then the car would say "hmmm, this human must not like that level of drops on the front window since he's manually activated it several time so I will do it for him next time". That's my idea of how the car can learn if you repeatedly need to manually wipe.
